Trailer Wiring Harness
The light duty trailer wiring
is
a six-wire harness
assembly. The optional heavy-duty trailer wiring is an
eight-wire harness assembly. The harnesses are stored
under the vehicle, along the passenger-side frame
crossmember on two-door vehicles or on the driver's
side corner frame crossmember on four-door vehicles.
The heavy-duty trailer wiring has a 30-amp feed wire
with an inline fuse located by the junction block. See
"Fuses and Circuit Breakers" in the Index. Both
harnesses have no connector and should be wired by a
qualified electrical technician. The technician can use
the following color code chart when connecting the
wiring harness to your trailer.
Dark Blue: Use for electric trailer brakes or
auxiliary wiring.
0
Red: Use for battery charging; it connects to the
starter solenoid (eight-wire harness only).
0
Light Green: Back-up lamps (eight-wire
harness only).
Brown: Taillamps and parking lamps.
0
Yellow: Left stoplamp and turn signal.
0
Dark Green: Right stoplamp and turn signal.
0
White (Heavy Gage): Ground wire.
0
White (Light Gage): Auxiliary stoplamp.
Securely attach the harness to the trailer, then tape or
strap
it
to your vehicle's frame rail. Be sure you leave it
loose enough so the wiring doesn't bend or break, but
not so loose that
it
drags on the ground. Store the
harness in its original place. Wrap the harness together
and tie
it
neatly so
it
won't be damaged.
