How to Repair or Install Trailer Wiring

Removing Your Tail Light
Remove the Tail Light

Removing the tail light to begin your trailer wiring installation.

This trailer wiring installation was performed on a Nissan Titan pickup, but your application will be similar. The first step is to get to the tail light wiring harness. This is usually done by removing the tail light assembly, but in some cases you can pop out a single harness from the back of the tail light. You just need access to the wiring. This truck's tail light assembly was easy to remove by taking out two bolts on the side of the truck bed then sliding the assembly out.
