Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.
Features:
Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the center of the rear bumper.
Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

It worked out well. This is the only way to go when adding trailer hitch. A real time saver.

Its installed but not working 100, Looks like GM never wired the vehicle for trailer lights. I thought plugging this harness in the socket that was there would fix this. All other lights work on the trailer except the running lights..I dont use it a night and not very often, but other than cutting wires dont know how to fix this. Leased vehicle only a year to go...so Im not cutting wires.

Tow bar and plug have worked without incident. Easy to hook up and easy to pull back hitch out. Very happy with it. Have recommended this website to many others.
