Good quality wiring
This is good quality wire for wiring up a trailer. The price was right and the product is exactly as described and work great on a small trailer I wired up.

Decent for the price.
*custom wiring for my project* This wiring harness has both ends and will get the job done. As described in the diagram, the ground wire is shorter than the rest. That was an issue for my build because it limited where I would set my ground wire, but if you read the description it’s hidden somewhere and describes that it would arrive like this by design. The wires are about 14GA thick I believe, not super cheap but I’m using wire looms to protect them against any damages.

Just as advertised. Installed easily.
Good solid wiring harness. It has separate left and right brake lines from the plug so that you don't have to run one wire to one taillight, and then run a separate wire from that one, across the trailer, to the other taillight. It made the job of running the wires much easier. The instructions looked clear as well. It would have been nice to have a cover for the trailer male plug included. But it sort of does, if you do what I did. The smaller harness which comes with it meant to be wired to your car has the female connector on it. I didn't need that harness, since my car already has its own harness meant to supply the trailer signals. So I cut off that female plug from the unneeded cable. I use that female connector as a cover for the trailer's male connector.
