Towing Package Factory Wiring Harness
The trailer tow preparation wiring harness is connected to the body wire harness. It is located at the right and left outer rear lamp unit connections. After installation is complete, a trailer tow stop/turn relay is secured to the harness behind the rear bumper fascia just below each outer rear lamp unit. A trailer tow stop lamp relay is located on the underside of each outboard end of the rear bumper reinforcement behind the rear fascia. The four-way trailer tow connector is located near the center of the rear fascia.
