DESCRIPTION Vehicles equipped with an optional factory-installed trailer towing package have a rear body wire harness that includes a trailer tow wiring take out (2) secured beneath the rear underbody with retainer clips (1 and 3). A molded connector (4) at the end of the take out is connected to a heavy duty, sealed, 7-pin trailer tow connector located on a bracket on the trailer hitch receiver. The rear body harness includes a second take out with a trailer tow relay connector bank and the four trailer tow relays that isolate the right turn signal, left turn signal, and brake lamp circuits of the vehicle from the electrical system of the trailer. The fourth relay in the connector bank provides a fused ignition switch output (run) source of battery voltage to the trailer tow connector through a trailer tow relay output circuit. The package also includes an adapter harness (stored beneath the left rear seat cushion of the vehicle when it is shipped from the factory) that adapts the 7-pin trailer tow connector to a standard, light-duty, 4-pin trailer tow connector. Refer to the appropriate wiring information.
