Nilight Heavy Duty 7 Way Inline Trailer Plug Extension 8FT w/Junction Box | Waterproof 7Pin RV Round Wiring Harness Extend Vehicle and Trailer Side Towing Car Color Coded for Campers Caravans Vans

This worked perfectly on our Forest River Camper, all wire colors matched our trailer side wiring. The diagram provided was a big help in identifying what wire controlled which set of lights, etc. Installation was super easy and the junction box that comes pre-attached is very nice. Perfect fit with good quality wiring materials. Exactly what I was looking for.

good quality

I work on a fleet of open and enclosed utility trailers. As each trailer comes in for wiring and light issues, I have been converting them over to this as it makes a simpler task of wiring the lights and brakes. It keeps everything neat and tidy and out of the weather. I like the longer whip because I can trim the length if I have to. So far I have had no issues on the trailers I have upgraded to this.

Solid and durable! The Nilight 7-way plug is easy to install, weatherproof, and works perfectly for my trailer setup. Great quality and reliable connections.

Great quality, but all the wiring was not in the correct color orientation. Brown(Running) was Green (Curbside) Green(Curbside) was Brown (Running) Yellow (Roadside) was Red (Reverse) Only Ground (White) was correct. Black is constant hot. Otherwise a good product, easy to install besides figuring out correct pattern and rearranging busbar since I had limited wire for my setup. Clean installation and doesn’t look tacky. Thanks!

The confusion about wire color is because there are 2 different but identical looking 7 way plugs. This is a RV Standard plug and the coloring matched my new truck perfect. There is also an SAE Standard, this junction box will work but wires have to be swapped. Check the plug cap on vehicle to see what you have, both standards are very easy to look up. It is plastic so I put it on a protected area of trailer. Lights and brakes work great on trailer I use to pull tractors, I will be swapping all my trailers over to this as needed.

Excellent Product easy This product will make any trailer look like million dollar one

I’ve bought a few of these now to re wire my trailers. They work great

Really impressed with this NiLight 7 way harness and junction box. The quality of the coating, right back to the junction box, is 2nd to none! They included some plugs and grommets for wiring which makes waterproofing on my end more simplified. All the wiring was as shown in the diagram and super simple to add my wiring harness into the junction box. The seals appear to seat well and the box is solid once mounted to the frame. I added some NiLight 18W (low amperage draw, still super bright!)spot lamps to the reverse circuit, bumper mounted. Should make those late night pull-ins to site easier😉
