The two bonded wires are a pain!In order to keep the dang thing from snarling itself into a rat's nest you need to tape the dang thing. Not a huge issue and for the price it got the job done but if I wasn't simply using thins for a jerry-rigged setup so I can have light to transport my new truck camper home, I would return it. I would NEVER use this as a long-term wire harness.

My trailer has two harnesses. One from the hitch to the rear, and one connects to it and splits to each tail light. The first one rotted the insulation from the hitch end and was shorting. This one replaced it perfectly.

Just what I needed. Original wiring from tow vehicle to the breakaway on the utility trailer was bad. Great price and works great.

Ths was easy to install once I found my cars wiring diagram on-line. The Ground wire was much shorter than the others so I spliced onto it so I could terminate all wires at the same point. Easy and quick to install.
