If you need to tow a light-duty trailer with a standard four-way round pin connector you can also get an adapter from your dealer.
Camper/Fifth-Wheel Trailer Wiring Package
The eight-wire camper harness is located under the front edge of the pickup box on the driver's side of the vehicle, attached to the frame bracket. A
connector will have to be added to the wiring harness which connects to the camper.
The eight-wire harness contains the following camper/trailer circuits:
-
Yellow: Left Stop/Turn Signal
-
Dark Green: Right Stop/Turn Signal
-
Brown: Taillamps
-
White: Ground
-
Light Green: Back-up Lamps
-
Light Blue: Center High-Mounted Stoplamp (CHMSL)

If your vehicle is equipped with the "Heavy-Duty Trailering" option, please refer to Heavy-Duty Trailer Wiring Package , earlier in this section.
When the camper-wiring harness is ordered without the heavy-duty trailering package, an eight-wire harness with a seven-pin connector and separate
CHMSL connector are located at the rear of the vehicle and are tied to the vehicle's frame.
