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.

Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side rear bumper. You will have to lower your muffler to access this harness.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your rear cargo area.
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.
