Towing Requirements - Trailer Lights AND Wiring
Whenever you pull a trailer, regardless of the trailer size, stop lights 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 Fig 1 and Fig 2.
