Has anyone installed the wiring for the trailer wiring harness yet? I just received my receiver and the harness, but their is absolutely no instructions on where to begin. I know it isn't a terribly complicated thing to do, but it would have been nice for just a little bit of direction; like where is the best path for wires and such. The receiver hitch install looks very simple, especially with the instructions and will likely take just a few minutes having it on a lift to work on. The wiring however...well Ford didn't include anything. Will be installing this week and will give some feedback, just wondering if anyone might have some advice to get me in the right direction.
