Trailer Wiring Harness
Heavy-Duty Trailer Wiring Package
If your vehicle is equipped with a trailer towing package,
the rear bumper harness will have a seven-pin
universal heavy-duty trailer connector attached to a
bracket on the hitch platform.
The trailer towing harness contains the following seven
trailer circuits:
•
Yellow: Left Stop/Turn Signal
•
Dark Green: Right Stop/Turn Signal
•
Brown: Taillamps
•
White: Ground
•
Light Green: Back-up Lamps
•
Red: Battery Feed
•
Dark Blue: Trailer Brake
If you are charging a remote (non-vehicle) battery, turn
on the headlamps to boost the vehicle system voltage
to properly charge the battery.
Trailer Brake Control Wiring Harness
The wires for the trailer brake control are taped to a
wiring harness under the instrument panel. The trailer
brake control harness will contain the following
labeled wires:
•
Dark Blue Wire (#47): Trailer Brake
•
Red Wire (#242): Batt ‘‘+’’
•
Light Blue Wire (#20): Brake Lights
•
Black Wire (#2050): Brake Ground
Trailer Recommendations
You must subtract your hitch load from the CWR for
your vehicle. Weigh your vehicle with your trailer
attached, so that you won’t go over the GVWR or
the GAWR.
You’ll get the best performance if you spread out the
weight of your load the right way, and if you choose the
correct hitch and trailer brakes.
For more information, see Towing a Trailer on page 4-47
