Review: Perfect for our camper! - 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 upgrade
*by T***Y on November 21, 2025*

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.
