Trailer Wiring Harness
If you have the optional trailering package, your vehicle
will have an eight-wire harness, including the center
high-mounted stoplamp battery feed wire. The harness
is stored on the passenger’s side of the vehicle near
the rear wheel well. This harness has a 30 amp battery
feed wire and no connector, and should be wired by
a quali ed electrical technician. After choosing an
aftermarket trailer mating connector pair, have the
technician attach one connector to the eight-wire trailer
harness and the other connector to the wiring harness
on the trailer. Be sure the wiring harness on the trailer
is taped or strapped to the trailer’s frame rail and
leave it loose enough so the wiring doesn’t bend or
break, but not so loose that it drags on the ground.
The eight-wire harness must be routed out of your
vehicle between the rear door and the oor, with enough
of the harness left on both sides so that the trailer or
the body won’t pull it. If you do not have the optional
trailering package, your vehicle will still have a trailering
harness. The harness is located near the passenger’s
side rear wheel well. It consists of six wires that may be
used by after-market trailer hitch installers.The technician can use the following color code chart
when connecting the wiring harness to your trailer.Brown: Rear lamps.
Yellow: Left stoplamp and turn signal.
Dark Green: Right stoplamp and turn signal.
White (Heavy Gage): Ground.
Light Green: Back-up lamps.
White (Light Gage): Center High-Mounted Stoplamp.
Blue: Auxiliary circuit (eight-wire harness only).
Orange: Fused auxiliary (eight-wire harness only).
Store the harness in its original place. Wrap the
harness together and tie it neatly so it won’t
be damaged.
