4-51 Trailer Wiring Harness
The trailer wiring harness is an eight-wire harness
assembly. The harness is stored under the vehicle, on the
driver's side corner frame crossmember. The harness has
a 30
-amp feed wire with an inline fuse located by the
junction block. See ªFuses and Circuit Breakersº in the
Index. The harness does not have a 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.

Red: Use for battery charging; it connects to the
starter solenoid.
Light Green: Back
-up lamps.

Brown: Taillamps and parking lamps.

Yellow: Left stoplamp and turn signal.

Dark Green: Right stoplamp and turn signal.

White (Heavy Gauge): Ground wire.

White (Light Gauge): 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.
