TRAILER TOW WIRING
Vehicles equipped with an optional factory-installed trailer towing package have a rear body wire harness that includes an integral trailer tow
wiring take out that connects to a heavy duty, sealed, 7-pin trailer tow connector located in the rear bumper. This harness includes an adapter
harness that adapts the 7-pin trailer tow connector to a standard, light-duty, 4-pin trailer tow connector. Refer to the appropriate wiring
information.
