Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for
more on this. Things that are especially important
in trailer operation are automatic transmission fluid
(don’t overfill), engine oil, axle lubricant, belt, cooling
system and brake system. Each of these is covered
in this manual, and the Index will help you find them
quickly. If you’re trailering, it’s a good idea to review
these sections before you start your trip.
Check periodically to see that all hitch nuts and
bolts are tight.
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 is fused in the engine compartment fuse
block. See “Fuses and Circuit Breakers” 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.
D
Dark Blue: Use for electric trailer brakes or
auxiliary wiring.
D
Red: Use for battery charging; it connects to the
starter solenoid.
D
Light Green: Back-up lamps.
D
Brown: Taillamps and parking lamps.
D
Yellow: Left stoplamp and turn signal.
D
Dark Green: Right stoplamp and turn signal.
D
White: Ground wire.
D
Light Blue: 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.
