Review on Jeep Commander Compatible 4-Way Flat T-One T-Connector Harness by Tekonsha by William Dean

This is a first class product that solves trailer headlight wiring problems. Personally, as a car enthusiast, I don't mess with the wiring, but that's really not necessary with this kit. All but 1 ground connection are plug and play. The connections seem very strong and fit together well, I've added quite a bit of dielectric grease and would be absolutely surprised if this kit ever caused any problems. I spent about 90 minutes installing it, trying to get every plug, box and cable as tucked and hidden as possible and I'm very happy with the end result. So unless you're into anal like me, chances are you will in under an hour.
