I need to replace the 7 pin connector/ cable on my camper.

I just cut half of my damaged wire, and mounted a 7 pin junction box on the tongue directly behind the battery. I had to get boxed steel, prime, and paint black. I did not want to drill directly into the trailer frame. Ran the shortened cable to the box with ring terminals, and mated an e-trailer 6 foot 7 wire plug wire color for color. Easy DIY repair job, and has ports to run additional wires out to pumps, poop cannons, and other 12vt accessories.
