Review on CURT 56335 Custom 4-Pin Trailer Wiring Harness, Vehicle-Side for Ford Escape, Black by James Roberts

Very easy to install. Watch the video, it's much better than the small picture in the instructions. Some have mentioned that the green wire is too short. The manufacturer must have taken note of this, because that is now more than enough. I had zero problems. I used a spade connector connected to one of the sockets in the rear fuse box as shown in one of the test images. The factory wiring harness will easily handle the light load generated by the trailer lights. I installed and tested it in less than an hour. Works great and all wire connections are made in the car unlike other methods of plugging into a trailer socket. Costs money.
