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:

Dark Green: Right Stop/Turn
Signal
.

.

.

*The fuses for these two circuits are
installed in the underhood electrical
center, but the wires are not
connected. They should be

for Tow/Haul Mode, turn on the
headlamps as a second way to
boost the vehicle system and
charge the battery.
