Trailer Wiring Harness
Your vehicle is equipped with one of the following
wiring harnesses for towing a trailer or hauling a
slide-in camper.
Basic Trailer Wiring
All regular, extended cab crew cab pickups have a
six-wire trailer towing harness.
The six-wire harness is located at the rear of the vehicle
and is tied to the vehicle’s frame. The harness requires
the installation of a trailer-wiring harness connector,
which is available through your dealer.
The six-wire harness contains the following
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 you need to upgrade your trailer wiring harness, an
additional 2–wire harness and 7 pin universal trailer
connector are available from your dealer.
