Basic Trailer Wiring
All regular, extended cab and crew cab pickups have a seven-wire trailer towing harness.
For vehicles not equipped with heavy duty trailering, the harness is secured to the vehicle's frame behind the spare tire mount. The harness requires the installation of a trailer connector, which is available through your dealer.
If towing a light-duty trailer with a standard four-way round pin connector, an adapter is available from your dealer.
