Great quality and easy to install
The LIMICAR Trailer Wiring Harness Kit is a solid choice for anyone needing to wire up a trailer. The 25-foot length gives plenty of room to work with, and the 4-flat extension connector fits securely. The wires are well-insulated and feel durable, so you don’t have to worry about wear and tear. Installation was straightforward, even for someone like me without much experience. If you need a reliable wiring kit, this one is definitely worth it!

Works with modification
18' boat and 25' of wire did not make it to the lights. Tonge to lights was 30'. Could not find a longer harness so I had to splice more wires.

Highly Recommend
So much wire, you can wire a 10ft by 8ft trailer. With enough left over to wire a full size pickup truck for 4 pin trailer wiring.

Good quality
Good quality materials and came with everything needed to replace a damaged wiring harness I had to replace. I only needed 9 feet so I had a lot of extra Length to work with. It was very easy to install and I would buy this again.
