Trailer Wiring Harness
Heavy-Duty Trailer Wiring Harness Package

The vehicle has a seven-pin universal heavy-duty trailer connector attached to the rear bumper beam next to the integrated trailer hitch.
The seven-wire harness contains the following trailer circuits:
- Yellow: Left Stop/Turn Signal
- Dark Green: Right Stop/Turn Signal
- Brown: Taillamps
- White: Ground
- Light Green: Back-up Lamps
- Red: Battery Feed*
- Dark Blue: Trailer Brake*
*The fuses for these two circuits are installed in the underhood electrical center, but the wires are not connected. They should be connected by your dealer or a qualified service center.
If charging a remote (non-vehicle) battery, press the tow/haul mode button located at the end of the shift lever. This will boost the vehicle system voltage and properly charge the battery. If the trailer is too light for tow/haul mode, turn on the headlamps as a second way to boost the vehicle system and charge the battery.
