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!
