This weekend I spent some time working through the unfinished items on the truck build. In my rush to get the truck ready for SEMA I was focusing on the things that needed to work vs the nice to have options.

The two items were the rear running lights and the backup lights in the bumper. I really hate cutting into the factory wiring harness. The workmanship is so high, these things will last many many years. As soon as you cut into them however they are typically worse. Since the tail lights are LED the wires are also very thin.

Since I am not towing, I decided to use the 8 pin trailer wiring harness and a trailer wire to plug into the factory electrical.



Lots of benefits doing it this way as the harness is fused and has plenty of capacity and I can just use the a trailer wiring kit and I am good to go with an already made system.

I have power wires for everything needed including the running lights, backup lights as well as my off road chase lights.



In my opinion it’s worth spending time on making the truck wiring bullet proof. Everything soldered, and wrapped with marine grade adhesive lined heat shrink tubing.

It does take lots of time.

But after a few hours of re routing the factory F150 harness and making up the extension harness I had light.

Here are the backup lights in the bumper. The kit backup lights are excellent.
