MOUNTING SYSTEMS WITH ALUMINUM TRIM
There are two methods for mounting the display panel into your dash. The first method is
to cut an opening in the dash the size of the inside lip and “sandwich” the dash between the
bezel and the mounting plate. The second method is to cut an opening in the dash the size of
the outside of the bezel and mount the entire display assembly from the back using six #10 or
#8 mounting studs attached to the back of the dash.
Figure 1 shows method #1 with a steel or thin fiberglass dash. Figure 2 shows method
#1 with a thick fiberglass or wood dash. Figure 3 shows method #2.

Method #1
Cut a rectangular hole where you want the dash mounted that is 1-11/16” tall x 17” long.
Next round the ends to match the bezel. The hole should be 18-11/16” long in the center from
end to end.
Remove the six screws that secure the mounting plate to the display panel. Next remove
the eight screws which attach the bezel to the mounting plate.
For thin dash material, place several strips of foam tape on the front of the mounting
plate. These will be compressed down when it is mounted to the dash.
Place the lens and bezel into the opening in your dash. Place the mounting plate up from
behind the dash and secure it to the bezel using the eight pan head screws. The screws with go
through the lens and thread into the bezel. Do not over tighten these screws. Just tighten them
so that the bezel is held in place securely.
Next attach the display system to the mounting plate using the six screws. Make sure
that the display panel is aligned properly with the flat gray cable coming out on the top side.

Method #2
Cut a rectangular hole where you want the dash mounted. The hole should be at least 2”
tall x 17” long rectangular with the ends rounded so that the center of the hole is 19” long.
Mount the six #8 or #10 studs to the back of your dash so that they line up with the
display system mounting holes. You can place the display system into the dash and use a
marker or pencil to mark the stud locations.
Next place the display system onto the studs and tighten it up from the back.

CONTROL BOX MOUNTING
Once the display panel is in place, mount the control box within reach of the ribbon cable
on the display panel (approximately 3 feet). Pick a mounting location that will allow you access
to wire all of the inputs on the control box. Double sided tape, hook and loop fasteners, or
screws in the two tabs on the case work fine for securing the control box under the dash.
When selecting a mounting location, avoid placing the control module next to, or
just opposite of the firewall, from ignition components, ie: Ignition coil, HEI, etc. Ignition
components can emit tremendous amounts of electric noise, affecting the operation of
electrical components.
Wiring the control box into the vehicle
While the control box contains several connections, the wiring is straightforward.
Depending on how many auxiliary functions you want displayed, not every terminal will be used
in most applications. Below we describe the function of each terminal, what they do, and how to
wire them.

TERMINAL DESCRIPTIONS
Status LED
This LED is located at the corner of the control box, next to the GROUND terminal. The
LED is used for diagnostics.
• A steady flash, on and off, about one second apart indicates the system is powered and
operating normally.
• On steady indicates low power, below 9V, at the POWER terminal (the displays will also
generally be dim).
• Not flashing or lighting indicates loss of power or ground.
GROUND
This is the main ground for the display system. A wire should be run from this terminal to
the vehicle’s main chassis ground. Use 18 AWG or larger wire to ensure sufficient grounding.
Proper vehicle grounding is extremely important for any gauges (or electronics) to
operate correctly. The engine block should have heavy ground cables to the battery, frame, and
firewall. Failure to properly ground the engine block or the control box can cause
incorrect or erratic operation.
8
MAN 650067:F
POWER
Connect the POWER terminal to accessory +12V power from the fuse panel or vehicle
wiring harness. This terminal should have power when the key is on or in accessory position.
In addition to powering the display system, this is also where the voltmeter gauge reads the
vehicle electrical system voltage. The supply source should be a fused 5 - 20 amp circuit; the
system only draws about 1 amp, so sharing an existing accessory circuit will be generally be
fine. Use 18 AWG wire to ensure the system receives a sufficient power feed.
*** Never connect the control box to a battery charger alone. It needs to have a 12 volt
battery connected to it. Battery chargers have an unregulated voltage output that will
cause the system to not operate properly and may cause damage to the control box.
TACH
Depending on the type of instrument system that you have, there may be a bar graph
tachometer, a digital tachometer, or both. Connect the TACH terminal to the ignition system.
On vehicles using a separate ignition coil, connect to the negative side of the coil. The negative
side of the coil will be the wire that goes to the points or electronic ignition module. For GM HEI
ignition equipped motors, connect to the terminal marked “TACH” or on some systems a single
white wire with a spade terminal on it. On some aftermarket ignition systems, connect to the
TACH output terminal. On computer controlled ignition systems consult a service manual for
the wire color and location. With a magneto system, connect to the kill wire for the tach signal.
Do not connect the TACH terminal to the secondary, or high voltage side of the ignition
coil.
To ensure that the ignition system does not interfere with any other dashboard functions,
do not run the tachometer wire alongside any other sender or input wires. DO NOT USE SOLID
CORE SPARK PLUG WIRES WITH THIS DASHBOARD SYSTEM. Solid core ignition wires
cause a large amount of electromagnetic and radio frequency interference which can disrupt the
system operation.
The tachometer is compatible with almost all gasoline engines. The engine cylinder
selection, display update rate, tach signal type, and rpm warning point can be adjusted in the
setup menu under “TACH”. If a diesel engine is being used then you will need a tach interface,
such as Dakota Digital’s DSL-1 or DSL-2. Be aware of the cylinder setting when using computer
outputs or reading the tach signal from an ECU. GM LS1 engines require the tach to be set up
for a 4 cylinder, low voltage signal when reading from the ECU even though it is a V8 engine.
WARN
The WARN terminal is an output for a relay or small light. The output is ground-activated
when the preset rpm limit is exceeded. This output can turn on a 4 Watt or smaller 12 volt bulb
or can activate a relay to turn on a larger bulb. To wire a warning light to this output, connect
one wire from the bulb to 12 volt accessory power and connect the other wire to the WARN
terminal.
DIM
The gauges are designed to dim down when the headlights are turned on. This is to
reduce the display intensity at night so the gauges do not cause eye strain or reduced night
vision. Connect this to the tail light or parking light circuit so that it has 12 volts whenever the
headlights are on. When this terminal does not have power, the display system will be at full
brightness. When power is applied, the display dims to an adjustable level.
The night brightness level is adjustable two different ways. This preset brightness is
adjusted in the setup menu “NIGHT”. See ADJ SND for a description of the second method.
By default the system will dim to about ½brightnes s when DIM terminal gets +12V.
9
MAN 650067:F
SPD +
This terminal is used to supply power to Dakota Digital speed sensor SEN-01-5. This
supplies 5V DC to the sensor and should not be hooked up to anything else. Connect the red
wire from the SEN-01-5 to this terminal.
If you are using a 1-wire VSS output from a computer or a two wire pulse generator this
terminal should be left open.
***DO NOT use this terminal to power any other devices; it is a low current +5V output.
SPD SND
This is where the vehicle speed sensor (VSS) connects. The signal supplied to this
terminal will be used by the control box to calculate the speed reading on the display and also
for calculating and saving odometer mileage.
Dakota Digital supplies a 3-wire sensor for most of its kits, SEN-01-5. If you are using
this sensor, the white wire is the speed signal; connect to SPD SND. The red and black wires in
the cable are power and ground (5V DC) and their connection is discussed in SPD + and SPD -.
For two wire speed sensors such as a cable driven pulse generator, the polarity of the
wires does not matter. Connect one wire to the SPD – (Ground) and the other to the SPD SND
terminal. The speed sensor ground wire should be brought back to the control box to ensure a
proper signal is received. Twisting the ground and signal wires around each other provides an
additional level of interference protection. The speed signal wire should not be routed alongside
tach, ignition, or other high current or high voltage wires.
For vehicles which have a vehicle speed signal from a transmission sensor or ECM, tap
into the VSS wire and connect it to the SPD SND. Consult a vehicle service manual or wiring
diagram to determine wire color and location.
This system can accept 4000 ppm – 128,000 ppm speed signals with room for
adjustment. The speedometer is fully adjustable and calibration is discussed in a later section.
***Failure to calibrate the speedometer may cause your odometer mileage to
increase very rapidly if the speedometer is reading too fast.
*** The speed signal wire should NOT be routed alongside ignition or other high
current/voltage wires.
SPD –
This terminal is used for speed sensor ground. This insures a proper ground as well as
providing proper hook-up for a twisted pair of wires, or a solid state sensor. Only ground the
speed sensor here. If you are using a single wire output from a computer for the VSS then this
terminal should be left open.
SPD OUT
This terminal can be used to supply a speed signal to auxiliary devices such as a cruise
control or radio volume adjustment. The output is scaled to the input speed signal coming into
the SPD SND terminal. It can be set to 2000 PPM or 4000 PPM.
***If you are using the bus speed signal option this output will NOT work.
SW 2 (-) or Tach switch
The SW 2 terminal is used for selecting the various rpm, engine, and warning displays
and also for entering the demonstration mode. The SW 2 input is activated by a ground
connection. The push button switch supplied (or any momentary normally open switch) is wired
by connecting one terminal to SW 2 and the other terminal to a ground. When the button is
pressed and released, message options for the current screen will change.
10
MAN 650067:F
To enter DEMO mode, press and hold switch 2 while turning the key on. The system will
light up and say DAKOTA DIGITAL on the message readout, release the switch and the system
will stay in demo mode until the power is cycled off and back on without the switch held.
SW 1 (-) or Speed switch
The SW 1 terminal is used for selecting the various speed, distance, and performance
screens and also for entering the setup menu. The SW 1 input is activated by a ground
connection. The push button switch supplied (or any momentary normally open switch) is wired
by connecting one terminal to SW 1 and the other terminal to a ground. When the button is
pressed and released, the message display screen will change. When the button is pressed
and held for a few seconds, any re-settable information displayed will be zeroed.
ADJ SND
The ADJ SND terminal is an optionally used input that allows you to have control over the
dimming brightness. By default, the system will dim to approximately half brightness when the
DIM terminal has power, +12V, but this level is adjustable in the NIGHTsetup menu. Using the
ADJ SND terminal allows you to have a dash mounted control to vary the brightness while the
headlights are on. This requires Dakota Digital’s DIM-1 kit; a stock headlight rheostat will not
work.
The DIM-1 has two wires, one connects to the ADJ SND terminal and the other connects
to ADJ - ground. The dash mounted dimmer will only vary the display brightness when the DIM
terminal has power, +12V.
ADJ –
This terminal provides a ground reference for the optionally installed DIM-1 for dash
mounted dimming control. One wire from the potentiometer will connect to the ADJ – terminal,
the other connects to the ADJ SND.
*This terminal should not be used for grounding other sensors or devices or damage to
the control box will occur. If not using a Dakota Digital DIM-1, this terminal should be left
open.
WTR SND
The water temperature sender included with this system must be used. Other
senders will cause incorrect readings or damage to the control box.
The supplied sensor, Dakota Digital SEN-04-5, is a 100-300ºF(40-150ºC) temp sensor.
The sender mounts on the engine block or into the intake manifold so that the end of the sensor
is in the engine coolant flow. It has 1/8” NPT threads, adaptor bushings may be used to adapt it
for various applications.
The water temp sensor has two wires coming from the harness. One wire will connect to
the WTR SND terminal; the other wire will connect to the WTR –. It does not matter which wire
goes into either location.
Due to the construction of the sensor, readings at lower temperatures below 100 ºF will
be inaccurate. The sensor is designed to be accurate from approximately 100 ºF - 300 ºF.
WTR –
This is the ground reference used for two-wire water temp sensors. This will connect to
one of the wires from the Dakota Digital SEN-04-5. The other wire will connect to the WTR SND
terminal, and it doesn’t matter which wire goes into either location.
11
MAN 650067:F
OIL +
This terminal is used to supply power to Dakota Digital pressure sensor SEN-03-8. This
supplies 5V DC to the sensor and should not be connected to anything else. Connect the red
wire from the SEN-03-8 to this terminal.
***DO NOT use this terminal to power any other devices; it is a low current +5V output.
OIL SND
The oil pressure sender included with this system must be used. Other senders
will cause incorrect readings or damage to the control box.
The supplied sensor, Dakota Digital SEN-03-8, is a 0-100 psi solid state pressure
sensor. The sender can mount on the engine block or in an oil pressure line off of the block.
The sender has 1/8” NPT threads. Adaptor bushings may be used to adapt it for various
applications.
The oil pressure sensor has three wires coming from the harness, plus one bare shield
wire. The WHITE wire will connect to the OIL SND terminal, the RED to OIL + (5V DC), and the
black and bare shield wire to OIL –. Do not route the oil sender wire alongside a spark plug wire
or other high current or high voltage wires. Doing so can cause incorrect or erratic gauge
readings.
If the oil pressure drops below an adjustable warning point, the reading will flash as a low
oil pressure warning. The default warning point is 10 psi. If the oil display shows “—“ this
indicates that the control box is sensing a short to ground or out-of-range error from the sender
or sender wire. If the oil display shows “EEE” this indicates that the control box is sensing an
open circuit or out-of-range error from the sender. If either indication remains on the display,
inspect the sender wire for damage, check the routing of the sender wire, check the sending unit
grounding, and check that the correct sending unit is connected.
OIL –
This is the ground reference used for three-wire pressure sensor. This will connect to the
black wire as well as the bare silver shield wire from the Dakota Digital SEN-03-8.
***The bare wire is the shield wire, connect this wire to the OIL – along with the black wire
***DO NOT connect this terminal to any other devices
FUEL +
This output is not typically used. It is a low current +12V supply for powering solid state
fuel sensors. Currently, it does not have an application for any Dakota Digital fuel level sensors.
***This terminal should not be used with a typical resistive type fuel sensor. For
most applications, leave this terminal open. Do not try to power other devices from this
terminal or damage to the control box will occur.
FUEL SND
The fuel gauge sending unit is not normally supplied because the display system can use
the existing fuel sending unit that is already in the tank in many cases. The sending units that
are compatible with this system are as follows: GM, Ford, VDO, and Stewart Warner. It is also
possible to program in a custom setting for senders that are not pre-programmed into the
system.
Dakota Digital recommends that you run two wires back to the fuel level sensor to insure
proper grounds. Use the FUEL - and FUEL SND terminals and run a twisted pair of wires back
to your fuel level sensor. Connect the FUEL - terminal to the fuel level sensor body or a
mounting screw to insure the sensor is sufficiently grounded. The other wire is the sensor signal
which goes to the FUEL SND terminal.
12
MAN 650067:F
If your wiring harness already has a single wire routed through the vehicle for the fuel
sender, then it may be used. If using a wire from an existing harness, make sure that the wire
does not have power. The fuel sender gets power from the control box only. Fuel senders
reference their ground from the sender mounting plate. Make sure that a ground wire is
connected from one of the sender mounting bolts to the vehicle frame.
The fuel sender type is selected using the setup menu under “FUEL”. The settings are
discussed later in the setup section. Anytime the fuel level is below 10%, the reading will flash
as a warning of low fuel.
The fuel gauge will initially display “FL” until the fuel sender type has been set. If the fuel
display shows “ --” this indicates that the control box is sensing a short to ground or out-of-
range error from the sender or sender wire. If the fuel display shows “EE” this indicates that the
control box is sensing an open circuit or out-of-range error from the sender. If either indication
remains on the display, inspect the sender wire for damage, check the routing of the sender
wire, check the sending unit grounding, and check that the sender selection is set correctly for
the sending unit that is connected.
FUEL –
This terminal is used to provide a ground connection for the fuel level sensor. Dakota
Digital recommends that you use the FUEL - terminal and run a twisted pair of wires back to
your fuel level sensor. Connect the FUEL - terminal to the fuel level sensor body or a mounting
screw to insure the sensor is sufficiently grounded. One terminal on the sensor is the signal
which goes to the FUEL SND terminal
***For fuel level sensors that are attached to an electric fuel pump, or if you have
an electric fuel pump in the tank, make sure that the fuel pump is externally grounded to
the vehicle chassis. Attempting to ground the fuel pump to the Dakota Digital control
box will result in erratic operation and damage to the control box.
CRUISE (-)
The CRUISE terminal can be used as a “cruise engaged” indicator. The CRUISE input is
activated by a ground signal from a compatible cruise control harness. Whenever the CRUISE
input is grounded, the system will display a small “c” to the right of the speedometer.
WAIT (+)
The WAIT terminal can be used as a “wait to start” or glow plug indicator. The WAIT
input is activated by a 12 volt signal from the glow plugs. Whenever the WAIT input is powered,
+12V, the system will display a flashing “W” in the lower left corner of the message display.
GEAR (1 wire)
The GEAR terminal is used for the gear shift indicator. The indicator is built into every
system, but will not light up unless a Dakota Digital GSS-1000/2000/5000 gear shift sending unit
is connected, telling the system what gear the transmission is in. The gear shift sending unit is
not included with the system and must be purchased separately if desired.
The GEAR terminal will connect to the FIRST terminal on a GSS-1000 or to the 1-WIRE
terminal on a GSS-2000 or GSS-5000. Follow the instructions in the GSS manual for use with a
single wire display system.
NOTE: The system will automatically change to the gear display for a few seconds
whenever the gear position changes, even if viewing a different message screen.
13
MAN 650067:F
4x4 (-)
The 4x4 terminal can be used on four wheel drive vehicles. The 4x4 input is activated by
a ground signal from a switch on the transfer case. Connect a wire from this terminal to the
switch on the transfer case. Whenever the 4x4 input is grounded the system will display a
highlighted “x4” in the lower right corner of the message display.
RIGHT (+)
The RIGHT terminal is activated by a 12 volt signal from the turn signal flasher. When
this terminal has 12 volts, an arrow will light up to the right of the speedometer display. An
existing wire from the vehicle for the right turn indicator can be used or a new wire can be
connected from the turn signal flasher or power wire feeding the right turn signal bulb.
LEFT (+)
The LEFT terminal is activated by a 12 volt signal from the turn signal flasher. When this
terminal has 12 volts, an arrow will light up to the left of the speedometer display. An existing
wire from the vehicle for the left turn indicator can be used or a new wire can be connected from
the turn signal flasher or power wire feeding the left turn signal bulb.
HIGH (+)
The HIGH terminal is activated by a 12 volt signal from the headlight high beam wire.
When the terminal has 12 volts, an indicator will light up to the lower right of the speedometer
display. An existing wire from the vehicle for the high beam indicator can be used or a new wire
can be connected from the high beam side of the hi/low beam switch.
BRAKE (-)
The BRAKE terminal can be used as a brake system warning indicator. The BRAKE
input is activated by a ground signal from the brake pressure switch on the master cylinder or
from the parking brake set switch. Connect a wire from this terminal to the pressure switch on
the master cylinder or consult a vehicle service manual to determine color and location of an
existing wire. Whenever the BRAKE input is grounded, the system will display a flashing “B” in
the upper right corner of the message display.
CHECK ENG (-)
The check engine terminal is used with fuel injection ECM’s to display engine problems
and trouble codes. The CHECK input is activated by a ground signal from the ECM. Whenever
the check input is grounded, the system will display a flashing “E” in the upper left corner of the
message display.
When the ECM is placed into diagnostic mode, trouble codes can be read by counting
the flashes. Consult a service manual for the fuel injection system that you have for further
information on trouble codes.
With some ECM’s, a 12 volt light bulb may need to be connected in addition to the
CHECK input in order to provide proper current loading. In this case, both the bulb and our
display system indicator would come on when the check engine wire is “active”.

MAN 650067:F
SPEEDOMETER SETUP/CALIBRATION
There are two main methods for calibrating the speedometer, Auto Cal and Adjust. Auto
Cal requires that you have one measured mile marked out (1 km for metric). Adjust requires
you to follow another vehicle going at a set speed, use a handheld GPS with speedometer
function, or time yourself over a mile to determine your speed.
* Dakota Digital recommends you start with the Auto Cal method to get the speedometer
close. If you find it’s reading too fast/slow after the Auto Cal, then attempt the Adjust
mode.
• Press and hold SW1, then turn the key on and start the engine.
• Once the engine is running, release SW1. SET SPEED should be displayed.
• Press and hold the switch until “ - ” “SPEED” is displayed to go into the speed setup menus,
release SW1.
• Now you can press and release the switch to scroll through the sub-menus, “SENDER” “AUTO”
“ADJUST” “SERVIC” “OUTPUT” “DONE”. When you get to the desired sub-menu press and
hold the switch to select it.
Speed sensor setup (SENDER)
This menu is used to set the speed sensor input type. You can use the supplied pulse
generator or existing speed sensor for most applications. You can also read the speed signal
with the use of a future product called the bus interface module (BIM). Dakota Digital also offers
BIM that will allow you to read the speed signal from an ECU if you are installing the system in a
vehicle equipped with the OBDII port or a drivetrain from a newer vehicle, most 1996 and newer
vehicles have this.
If you are using a Dakota Digital pulse generator or feeding an ECU signal into the SPD
SND terminal, this is considered a “NORMAL” signal.
• When “SENDER” is displayed press and hold SW1 until you get “ -”
• Release SW1 and the current sensor selection will be displayed
• Press and release SW1 to toggle between “NORMAL”and “BUS”
• When the desired setting is displayed press and hold SW1 until “ -” “DONE” is displayed
• Release the switch to go onto the next sub menu item.
Auto Cal (AUTO)
This menu is used to calibrate the speed signal by driving a measured mile (or kilometer)
• When “AUTO” is displayed press and hold SW1 until you get “ -”
• Release SW1 and the primary speed unit will be displayed
• Press and release SW1 to toggle between “MPH” for miles per hour or “KMH” for kilometers
per hour. The setting saved here will be what the speedometer reads as well as the
units used to calculate odometer mileage.
• When the desired unit is displayed press and hold SW1 until you see the “ -” then release
SW1.
The speedometer will display “CAL” and the odometer should be reading “000000”, the
other displays should be lit and display normally(fuel, volt, water, and oil). Begin driving the
measured mile (or km). The odometer reading should start incrementing as you travel,
indicating the pulses received from the speed sensor or VSS. This is known as the pulses per
mile (PPM). Once you reach the end of the marked mile (or km), or are passing the marker,
press and release SW1. The displays will flash off, then everything should light up and the
speedometer should now be displaying your speed. Auto Cal is now complete and your
speedometer should be reading correctly.
17
MAN 650067:F
(Auto Cal continued)
NOTES: You do not have to drive at a constant speed nor do you have to avoid stopping
during Auto Cal. When completed, you do no need to stop, you may, but you can also
just press and release SW1 as you pass the 1 mile mark.
The message display cannot be used to determine when the mile has been driven, it’s
only there as a reference to indicate pulses are coming into the control box. Even if you
have an 8000 PPM sensor you may calibrate at 9xxx PPM (for example) due to gearing
and tire size.
Also be aware that the odometer miles are calculated from the speedometer cal value; if
it is not calibrated properly, the odometer miles could be higher/lower than actual.
***If you do not receive more than 2000 pulses during calibration the unit will error out.
Adjust Mode (ADJUST)
Adjust is different depending on what input signal is selected in the SENDERmenu.
• When “ADJUST” is displayed, press and hold SW1 until you get “ -” then release the switch.
• Now select the primary units by pressing and releasing SW1, “MPH” for miles per hour or
“KMH” for kilometers per hour.
• When the desired units are selected, press and hold SW1 until you see the “ -” then release
SW1.
If “NOMAL”is selected for the sender type it will allow you to adjust the signal that is being
supplied to the SPD SND terminal coming from a pulse generator or ECU. The fuel, volt, oil,
water, and tach will operate normally. The speedometer will show the speed reading and the
speed message display will say “ADJUST”. Begin driving at a known speed. Press and hold
SW1 to increase the speedometer reading; the next press and hold of SW1 will decrease the
speedometer reading. You can continue adjusting up and down as needed until the reading is
correct. When the speedometer is correct, stop and restart the system, by turning the key/power
off and then starting the vehicle back up. The new calibration will be saved when the power is
shut off.
If “BUS” is selected for the sender type, the speed signal should be coming into the AUX
I/O port through the use of a future BIM module. The adjustment ratio ranges from 75 – 125%
on this setting as it is assumed that the signal from the external device is the correct pulse rate;
there are only provisions for slight adjustment. The odometer will light up and show “CL xx” xx
is adjustable from 75 – 125 and is the percentage the input is corrected by. If set to 100 the
signal is uncorrected and whatever the BIM module is reading is displayed on the dash.
NOTES: For Adjust mode you can follow another vehicle, time yourself, or use a GPS as
a reference. A chassis dyno is another excellent way to use the Adjust mode.
Also be aware that the odometer miles are calculated from the speedometer cal value, if
calibrated properly, odometer miles could be higher/lower.
Service countdown meter (S-SET)
The service countdown meter or, S-SET, allows you to set a mileage value that will
decrease as the odometer miles increase. When the value gets to zero, a message “S DUE” will
appear on the message display on power up to remind you that service is due. This can be
used for routine maintenance reminders such as oil changes.
• When “S-SET” is displayed, press and hold SW1 until you get “ -” then release the switch.
The current service setting will be displayed.
• Press and release SW1 to increase the value from “OFF” then “500”-“7500” in 500 mile
increments.

BUS INTERFACE MODULE SETUP
The bus interface modules (BIM) are a future product added to Dakota Digital
instrumentation systems. They allow you to add auxiliary gauge functions, such as fuel
pressure, vac/boost, trans temp, etc., right into the system without having to add additional
gauges. All of the BIM readings are displayed below the tachometer bar graph display in the
message center. Switch 2 (SW2) is used to cycle through the various message screens.
More detailed instructions are supplied with the BIM units.

ODOMETER PRESET MENU
The control box will allow you to set the odometer miles to match your current odometer
reading, ONE time within the first 100 miles. Once the odometer has more than 100 miles,
this menu option will no longer be displayed. Make sure you have correctly selected the
units to be either MPH or km/h and calibrated your speedometer first. The odometer will
be set in the selected units. Once you have preset the miles, you cannot change it again
without sending to the factory.
WARNING!!: This only allows setting odometer to the nearest mile. Do not use tenths!
For example a mileage of 65432.1 should be set to “065432” using this method. If the
tenths digit is used, the odometer will read 10 times too high.
• Press and hold SW 1 while turning the key on.
• Release the switch and then press and release SW1 to get to the “-ODOM” setup menu.

TROUBLESHOOTING GUIDE
This is a list of some problems and their solutions which may be encountered when installing your
instrumentation system. If you cannot determine what the problem is or how to solve it, please call our
technical assistance line (605) 332-6513 or email [email protected].
* A note on vehicle grounding. *
The most common cause of problems with electric gauges and other sensitive vehicle electronics
is poor ground connections. The engine block has the highest ground currents of any point in the
vehicle. The ignition system, electric gauge senders, starter, alternator, etc. all use the engine block for
a ground point. Since the alternator is grounded directly to the engine block, all ground currents in the
entire vehicle must pass through the engine block while the engine is running. A weak or loose
connection can cause many unexpected problems that may be difficult to track down. The engine block
should have heavy ground straps to both the chassis and the body. The main negative cable from
the battery should be connected directly to the engine block.
