Wiring Instructions - Intellitronix DP2002W Installation Manual

Running wires
Wires need to be run between the digital dash panel boards and the supplied sensors, to send a
signal to each gauge, plus power and ground. Power should be a good clean, switched 12V source,
and ground should be solid bare metal such as engine block or unpainted frame members. How and
where you run these wires will vary depending on your preferences, and how your car is set up. A
good practice is to poke through into the engine bay via an existing grommet, and it is often easiest
to fish the wires though in a staggered manner if the grommet is tight. Tuck in the wire runs behind
existing components to achieve a clean look. Secure the wires with zip ties at intervals. Make sure
the new wiring doesn't interfere with gas or brake pedals. The rest is up to you.

WIRING INSTRUCTIONS

Note: Automotive circuit connectors are the preferred method of connecting wires. However, you
may solder if you wish.
Note: If doing an LS engine swap, pick up the tach signal wire from the ECM/ECU and then set the
tach switch to 4-cylinders. You may also need to order the Intellitronix LS Engine Swap Adapter Kit
– for Series 1, 2 and 3 engines. The part number is 8014LS. If you are getting the tach signal from
the ECU, the resistor in the adapter kit will help pull a stronger signal for the tachometer. If your
engine is a 4 cylinder, please call Tech Support at Intellitronix, as you may need to send the gauge
back to us to be reconfigured. There is no charge for this additional service.
Ground – Black This is the main ground for the display system. A wire should be run from this
board to the vehicle's engine block 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, senders, or digital dash panels can cause
incorrect or erratic operation.
Power – Red 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. Use 18
AWG wire to ensure the system receives a sufficient power feed.
Speedometer – White If your vehicle has a mechanical speedometer cable from the transmission,
disconnect it and thread the new electronic sensor onto the transmission. This unit comes with a 3-
wire sensor. If you are using this sensor, the white wire is the speed signal; connect this to the speed
signal wire on your gauge. The red and black wires in the cable are switched power (12VDC) and
ground, respectively. Twisting the ground and signal wires around each other will provide an
additional level of interference protection. The speed signal wire should not be routed alongside the
tachometer, ignition, or any other high-current or high-voltage wires. For vehicles which have a
vehicle speed signal from a transmission -- one wire goes to the speedometer, and the other to the
ground -- or ECM. Tap into the VSS wire (consult a vehicle service manual or wiring diagram to
determine the correct wire color) and connect it to the white speed sending wire on the digital dash.
Speedometer – White If your vehicle has an electronic vehicle speed signal from a transmission --
one wire goes to the speedometer, and the other to the ground -- or ECM. Tap into the VSS wire
(consult a vehicle service manual or wiring diagram to determine the correct wire color) and connect
it to the white speed sending wire on the digital dash. The speed signal wire should not be routed
alongside the tachometer, ignition, or any other high-current or high-voltage wires. Twisting the
ground and signal wires around each other will provide an additional level of interference protection
