Trailer Wiring Harness
Heavy-Duty Trailer Wiring Package
Your vehicle is equipped with the seven-wire trailer
towing harness. This harness with a seven-pin universal
heavy-duty trailer connector is attached to the rear
bumper beam. It is located 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 #
**If you are 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, you can turn on the headlamps
as a second way to boost the vehicle system and charge
the battery.
#The fuses for these circuits are installed in the
underhood electrical center, but the wires are not
connected. These circuits should be connected by your
dealer/retailer or a qualified service technician.
