  • Simplified my install.
Easy to follow instructions to plug in my front spot lights. I would recommend this before trying to hard wire lights into your fuse box.

  • Handy and complete
I wired an LED light strip into the front bumper of my F-150. This harness worked well, with an extension from the harness to the front light. We’ll worth it!

  • Very Simple & Easy

Used this harness to power a cooling fan for my Jeep YJ. Works great, cut and dry install

  • This is an excellent wire harness for an aux light application
This wire harness is very easy to install, and has quite sufficient length for any application that I could imagine. I had surplus for my fog light installation that I doubled up and zip-tied out of the way. The most difficult part of the installation, as is always, was routing it into the cabin, and finding a place to mouth the switch. It comes with a "snake-skin" sleeve, that I think will offer very good mechanical protection. ... show more
