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!

the harness was fine as a replacement, though the gauge of the wire was thin

My trailer didn't light up on a snowy day hauling my snow blower. It has LED lights and this fixed it's lights to work on my trailer hooked up to my 1994 pickup truck.

This is a perfectly good trailer wiring kit, not including lights obviously, but it is not an extension cable. Fortunately it looks like I will need this too, but the photos and wording imply it's an extension which it is not.
