The trailer wiring kit is suitable for trailers with a length and width not exceeding 80 inches.

I like a bunch of the nice little extras that are featured on this harness:Both legs are wrapped in a protective wire sleeve that will prevent chafing/rubbing/damage to the outer sheath of the wires inside once they are routed through the trailer.At the transition from the wires into and out of the sleeve, they have added very tough heat shrink that will keep things locked together.The ground wire already has a ring attached, which simplifies installation.The connector's cap has a very secure fit, which hopefully will do a really good job of keeping the connectors sealed against the elements.My brother has a trailer that has had electrical gremlins in it for as long as I can remember. I'm going to use this harness to re-wire the entire trailer for him, and I can't wait to finally have a trailer with all the lights working when I borrow it from him.

Wires are nice pliable. Connector is solid and fully attached. It has a protective sleeve is very nice add. There is heat shrink tubing is solid. Feels like it will last a good long time. There’s more than enough length that I can do what’s needed to do. Good price as well.

I got this for my 5x10 single axle trailer. It is nicer than the harnesses that come in the complete kits. The wiring feels like it is durable enough and I love that it is pre loomed to run down each side of the trailer. I usually add a ground wire and send it straight to each light and that helps with faulty grounds and flickering lights. There is room in the looming to do this. Good choice if you have a simple trailer setup to wire.
