WIRING: 3-PIN Connector
White/Red: Tachometer Input
When installing this system in TACH REFERENCE mode, this wire must be connected to a valid source of AC voltage. This wire allows the unit to sense the engine running. See Tach Section on Page 15 for more information.
Black: Chassis Ground
Connect to body metal of the vehicle using a sheet metal screw and a star washer to ensure a good ground. Keep the Ground wire short. Scrape away paint or debris from ground location.
WHITE: +12V or (-) 500mA NEGATIVE PARKING LIGHT OUTPUT:
Connect to vehicle parking light circuit at the back of light switch or if this is not possible, connect directly to one of the parking lights at the front of the vehicle. If your vehicle has a multiplex lighting system that requires a
NOTES: (1) Default parking light output is +12 volts. (2) Use an external relay for vehicles that draw excess current from extra running lights, light bars, or trailers. Parking light output is limited to +10 or
WIRING: 5-PIN Connector
Violet: (+) Door Pin Switch Input
Same as the GREEN wire below except this wire is used for vehicles that show a positive voltage (+12 volts) when the door is open and a ground when doors are closed as in many Ford, Lincoln, and Mercury vehicles.
Green: (-) Door Pin Switch Input
Identify the wire that reads ground when any door is open and 12 volts when all doors are closed. Some vehicles may have isolated door triggers. In this case you may need to run additional wires from other doors or go directly to the wire that triggers the vehicle’s interior dome light. Sometimes newer vehicles contain a separate body control module (BCM) where the door trigger circuit can be located. Most vehicles will NOT require the use of BOTH Green and Violet door trigger wires.
Blue: (-) Hood/Trunk Pin Switch Input
Input trigger for a grounding hood or trunk pin switch. Connect to existing hood and trunk pin switches that read ground when open. If no existing switches are available, install new pin switches if desired. Note: DO NOT mount new pin switches in water pathways.
