Thank you for purchasing the Vacuum Fluorescent Digital Dashboard from DAKOTA
DIGITAL, the leader in custom automotive electronics. Representing the latest electronics
dashboard technology for the street rodder, car, and truck enthusiast alike, the digital
instrumentation uses state of the art vacuum fluorescent display technology to give the driver up
to date and accurate information on the operation of his or her vehicle. As used in several
production automobiles, vacuum fluorescent displays give superior performance and visual
appeal over LCD or LED display systems. Emitting a blue/green light that can be filtered to a
wide variety of colors, the VFD system boasts excellent daytime visibility and while under
computer control, automatically dims for nighttime driving. Using microprocessor technology,
the digital dashboard gives the driver additional features and benefits not typically found on any
other brand or type of instrumentation. Digital accuracy and solid state reliability will give you,
the driver, quality service for miles down the road.
WARNING
The vacuum fluorescent displays are made of glass and should be handled with care. Use
extreme care around the glass evacuation tubes (small tubes at the bottom of each
display) as bumping them may cause breakage and render the display useless.
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
Once the display panel is in place, mount the control box within the connecting cable's
distance (approximately 3 feet) and secure to the underside of the dashboard. This case does
not have to be mounted to metal, but by doing so you will provide a better ground to the control
box. Align the connector in the socket and press firmly into the control box. The connector
locks will secure the connector.

Wiring the control box into the vehicle.
+12V
Connect the +12V terminal to accessory 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 senses the
vehicle electrical system voltage.
Use 18 AWG or larger wire to ensure the system gets good power.
Never connect this 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.
GROUND
This is the main ground for the display system. A wire should be run from this terminal to
the vehicle’s main ground location at the chassis or engine block. Do not use the dash or a
dash support brace for the ground connection.
Use 18 AWG or larger wire to ensure sufficient grounding. Proper vehicle grounding is
extremely important for the gauges to read and operate correctly. The engine block should
have heavy ground cables to the battery, frame, firewall, and body. Failure to properly ground
the engine block or the control box can cause incorrect or erratic operation.
DIMMING
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.
The default method is to have the system to dim to a preset level when the lights are
turned on. This preset brightness is adjusted in the setup menu “DIM”. See DIM ADJ for a
description of the second method.
DIM ADJ
The second method allows you to have a dash mounted control to vary the brightness
while the headlights are on. This requires a 10k potentiometer or Dakota Digital’s DIM-1 kit. A
stock headlight rheostat will not work. The dash mount dimmer has two wires, one connects to
the DIM ADJ terminal and the other connects to ground. The dash mount dimmer will only vary
the display brightness when the DIMMING terminal has power.
5
SPEED
The vehicle speed sensor (VSS) connects to this to tell the system how fast the vehicle is
moving. For two wire speed sensors, like the one Dakota Digital supplies with this system, the
polarity of the wires does not matter. Connect one wire to ground and the other to the speed
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 along
side ignition or other high current or high voltage wires.
For vehicles which already have a vehicle speed signal, tap into the VSS wire and
connect it to the speed terminal. You may have to consult a vehicle service manual or wiring
diagram to determine wire color and location.
This system can accept 4000 ppm – 128000 ppm speed signals. The sensor that Dakota
Digital provides is an 8000 ppm type. 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.
TACH
The gauge system has both a digital readout and a bar graph tachometer. 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 the tach terminal to
the terminal marked “TACH” or on some systems, to a single white wire with a spade terminal
on it. On MSD ignition systems, connect to the TACH output terminal. With 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 along side 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 and the alternator has a tach
output, then Dakota Digital’s DSL-1 interface will convert the alternator signal to operate the
tachometer.
WATER
The water temperature sender included with this system must be used. Other senders
will cause incorrect readings. 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. The sender gets its
electrical ground connection to the engine block through its threads. Do not use Teflon tape or
thread sealant on the sender threads. Doing so can cause incorrect readings or cause the
gauge to display an out of range indication. A sender with 1/8 NPT thread size is normally
included along with adapters to go to 1/4, 3/8, and ½ NPT. If the engine you have requires a
metric or non-standard thread size you can contact Dakota Digital for availability or check your
local auto parts dealer or hardware store for an adapter.
A single wire should be run from the terminal on top of the water sender to the control
box terminal marked WATER. If your wiring harness already has a wire routed through the
vehicle for the water temperature then it may be used. Do not route the water sender wire along
6
side a spark plug wire or other high current or high voltage wires. Doing so can cause incorrect
or erratic gauge readings.
If the water 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 water display shows “EEE”
this indicates that the control box is sensing an open circuit or out-of-range error from the
sender or sender wire. 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. The sending unit should be stamped with “VDO” and
“150°C”.

OIL
The oil pressure sender included with this system must be used. Other senders will
cause incorrect readings. If the sender mounting location is too small or is restricted, then pipe
fittings may be required to move the sender away from the restrictions. Oil pressure line may
also be used to remote mount the sender to the fire wall. The sender gets its electrical ground
connection to the engine block through its threads. Do not use Teflon tape or thread sealant on
the sender threads. Doing so can cause incorrect readings or cause the gauge to display an
out-of-range indication. If the sender is being remote mounted away from the engine, make
sure the sender case is grounded well. The sender has 1/8 NPT thread size. If the engine you
have requires a different thread size you will need to use an adapter to convert the thread size.
Adapters can be found at your local auto parts dealer or hardware store.
A single wire should be run from the terminal on top of the oil sender to the control box
terminal marked OIL. If your wiring harness already has a wire routed through the vehicle for
the oil sender then it may be used. Do not route the oil sender wire along side a spark plug wire
or other high current or high voltage wires. Doing so can cause incorrect or erratic gauge
readings.
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 “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 correct sending unit is
connected.

FUEL
The fuel gauge sending unit is not normally supplied with the system. The display
system will usually use the fuel sending unit that is already in the tank. 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. The Stewart Warner sender type is used by most after-market gauges. A single wire
should be run from the fuel sender to the control box terminal marked FUEL. If your wiring
harness already has a 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 get their ground from the sender
7
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 section on internal adjustments.
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.
SW 1 or Message switch
The SW 1 terminal is used for selecting the various speed, distance, warning, and
performance displays and also for entering the setup menu. The SW 1 input is activated by a
ground connection. The push button switch supplied (or any 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 will change. When the button is pressed and held
for a few seconds, any re-settable information displayed will be zeroed. When the service miles
and hour meter are displayed, pressing and holding the switch will only zero the service miles.
SW 2 or Demo switch
The SW 2 terminal is used for zeroing the hour meter display and also for entering the
demonstration mode. The SW 2 input is activated by a ground connection. The push button
switch supplied (or any normally open switch) is wired by connecting one terminal to SW 2 and
the other terminal to a ground. When the service miles and hour meter are displayed, pressing
and holding the switch for a few seconds will zero the hours.
To enter DEMO mode, press and hold the switch while turning the key on.
CHECK
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 switch to the warning messages and
“ENGINE” will be highlighted. This message can be cleared by pressing and holding switch 1.
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 our
CHECK input in order to provide proper current loading. In this case both the bulb and our
display system indicator would both come on when the check engine wire was set.
8
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 switch to the warning
messages and “BRAKE” will be highlighted. This message can be cleared by pressing and
holding switch 1.
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 switch to the message display and “CRUIS” will be highlighted.
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 the
system will switch to the warning messages and “WAIT” will be highlighted. This message can
be cleared by pressing and holding switch 1.
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 switch to the
message display and “4x4” will be displayed on the top left side. When signal turns off, the
system will display “4x2” on the message display.
HI BEAM
The HI BEAM terminal is activated by a 12 volt signal from the headlight high beam wire.
When the terminal has 12 volts, an indicator will be turned on in the lower right of the message
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 beam/low beam switch.
LEFT
The LEFT terminal is activated by a 12 volt signal from the turn signal switch. When this
terminal has 12 volts, an arrow will light up to the left of the message 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 switch.
RIGHT
The RIGHT terminal is activated by a 12 volt signal from the turn signal switch. When
this terminal has 12 volts, an arrow will light up to the right of the message 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 switch.
9
SHIFT
The SHIFT 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 SHIFT
terminal.
GEAR SHIFT INDICATOR INPUT
The GEAR terminal is used for the gear shift indicator. The indicator is built into every
system but it will not light up unless a Dakota Digital GSS-1000/2000/5000 gear shift sending
unit is connected to tell it what gear the transmission is in. The gear shift sending unit is not
included with the system and must be purchased separately. 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.
The gear display is selected in the setup menu under “GEAR”. The choices are no gear
display, standard transmission, or overdrive transmission.
When the gear shift sending unit is connected, the current gear letter will be highlighted
on the message display below the mileage readings.

SPEED CALIBRATION
There are two methods for calibrating the speedometer, auto cal and adjust. Either one
can be used. Auto cal requires that you have one measured mile marked out (km for metric).
Adjust requires you to follow another vehicle going at a set speed or timing your self over a mile
to determine your speed.
Auto Cal
When “AUTO” is displayed press and release the switch. The speedometer will display
“SEt”, the fuel, volt, oil, and water will display normally, and the message display will show
zeroes. You should now begin driving the measured mile. The message display will count the
number of pulses received from the sensor. The message display cannot be used to determine
when a mile has been driven. Once you reach the end of your marked mile, press the switch
again. The calibration is now done.

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 to dakotasupport@dakotadigital.com.
* A note on vehicle grounding. *
The most common cause of problems with electric gauges 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 all kinds of random
problems that may 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.

CLOCK
Wiring instructions for VFD systems with a clock built in.
Introduction:
The clock displays the current time in 12 hour format with an AM/PM indicator. The AM/PM indicator
appears as a dot that will be displayed in the upper left corner. The dot will be on every other 12 hour period (on
during AM and off during PM). The high brightness display matches our other Odyssey and STR series gauges
and has the same night brightness dimming capability. Features included are:
• Quartz accuracy.
• Night dimming feature.
• Very low standby power to prevent battery drain.
• High Visibility VFD display for sunlight readability.
Operation:
The gauge needs the red, orange, and black wires connected to operate. The red wire should have
switched 12 volt power from an ACC. point on the fuse panel. The orange wire should have constant 12 volt
power. The black wire should be connected to a good ground point. When the blue wire has 12 volts, it will dim the
display for night viewing.
Setting the time:
Using a small, thin object such as a pen or hairpin, press “set” buttons through front lens access holes.
The access holes are on the right side of the lens. Top “set” button advances hours, bottom “set” button advances
minutes.
