Review on BougeRV 7 Way Trailer Plug: Weatherproof Wiring Harness with Junction Box for RV Trailers, Campers, Caravans, and Food Trucks - Enclosed Trailer Accessories by Jeff Hall

I'm installing this on a standard gooseneck trailer, the box gives me a great central position to mount a light rig. There are two things I've noticed so far, although minor, bother them. 1) The construction site is isolated and there is no possibility of direct fixing to the ground. This forces me to add a ground wire from the trailer to the box. The lack of a connector/method to do this is not a problem on an RV, but a major problem on a standard or other service trailer. 2) Color codes do not match. It's documented that the blue wire from the standard connector was supposed to be "power", ie power from the vehicle's battery, but I found that it was connected to the headlights. It's minor, but you need to match that with the correct pinout. Again, this isn't a problem, but you should create more documentation to know that this happened.
