6ft 7-Way Trailer Plug Extension Wiring Harness - Plug-N-Play 7-Pin Trailer Wire Cable for Brake & Light Control, Suitable for RVs, Trailers, Campers and Other Towed Vehicles, 10-14AWG

I bought other wiring harnesses and they did not work. Follow the directions and everything on it. I ended up buying this one and it worked it wasted my time on the other two I would buy this again. I recommend people this product.

So I have had several versions of my trailer plug box which has EVERY plug on it from a 4 or 5 flat standard the 4 round that is seemingly not really use, a 5 and 6 round that I see rarely to the more standard RV round 7 flat and also the Heavy duty Semi truck 7 Round plug. I have a brake-turn separator that provides me the Brake and Turn separate for lighting that uses this option in the wiring. The trailer tail has a wiring diagram that actually matches the pinout of the plug whereas many others I have gotten do not. But RED is not usually right. Standard trailer wiring is Brown Green Yellow which is the tail, left and right white is usually ground in all wiring blue normally is brake, RED typically was REversse and Black is constant charging power from the vehicle I always thought those should be switched but I am not the industry. So long as you follow the included paper slip the wires match. ALSO I recommend that you get a trailer test plug that lights up for each pin function from the vehicle connection which is great if you need to find a blown fuse or wire issue in the plug so not a bad purchase to include with the cable. NOTE: I will add the Euro plugs just because I can.

Very easy to replace old cord on my travel trailer.

The insulation was stripped too far back, so that the strain relief clamp and water seal didn't grab the cord, but it was straightforward to take half an inch off the wires and reconnect them so that it assembles correctly.

I can only assume the one that I have shorts out occasionally this one appears to be of good quality have not tested it yet, but I think it will work

Fits snug, plug and play, spans the distance perfectly. Just what I needed in every aspect!

Great product

Got what I ordered simple to install
