Great kit for the price
It was delivered fast and packed well the kit was just as described and easy to installed I just pulled the old wires out one side at a time and as I did I replaced it with the new then hooked it up .

Ground wire is short.
Harness seems to be good quality, but FYI, the ground wire is only about 2 to 3 feet long. Description doesn’t mention that, so i only gave it 4 stars. The short ground wire wouldn’t work for my application since the trailer body tilts and I can’t securely ground the hitch.

Best trailer wiring on Amazon
Works perfect, very nice thick coated cables. Solid construction. No complaints, and way better than the other garbage. Bought this twice and will by for every trailer for now on. Length is good enough for most trailers I used it for my 4x8 folding trailer with an a frame tongue and had about 4 or 5 feet left if you run it down the center of the trailer you’ll have more but I ran mine through the rails in the side. Also the 4pin connector is sheathed so if it protects your vehicle wiring harness.
