Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Towing Requirements - Trailer Lights AND Wiring
Whenever you pull a trailer, regardless of the trailer size, stoplights and turn signals on the trailer are required for motoring safety.
The Trailer Tow Package may include a 4 and 7-pin wiring harness. Use a factory approved trailer harness and connector.
The electrical connections are all complete to the vehicle but you must mate the harness to a trailer connector. Refer to the following illustrations.
