Review on ABN Electrical Wire Connector Junction Box 1-Pack for Trailer, Camper, RV Light - 7 Gang/Pole Automotive Wiring Rewiring Solution by Donald Phi

So a little black box, so what? It is the heart of the trailer wiring harness that separates reliable trailer lighting from haphazard lighting at best. I installed this junction box as close to the center of my trailer as possible. This allowed me to run the shortest possible wire to each light. Since my trailer has brakes I needed a five wire harness and figured it would be better to use a seven wire connector so I don't have to carry around an extra adapter which of course could be out of place when I need it. . Then I had the feeling that I could also install reversing lights and additional power and have the complete package. This junction box isn't magic, but it has everything you need to have a weatherproof enclosure to keep your cable connections from corroding and failing at the worst possible moment. I also used clamps with built in heat shrink tubing to ensure my connections didn't get wet. It's true that you will need other materials besides this box, but consider these the foundation or heart of your trailer wiring kit.
