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 driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness.
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.

Being stuck in once place gets old really quickly! I'm so happy to know you're able to get out when you like again :)

It is still working great. Using to connect a 2016 GMC Terrain to a custom built kayak trailer.

Still impressed with the installation and the good fit. I have hauled various stuff in my 6 by 6 trailer, up to about 2500 lbs. Works fine. Doesnt feel loose. Doesnt squeak. Had several compliments on the look and subsequent referrals.
