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

Ok I bought 2 of these items. For the price you can't beat them. Pros: They are very useful. I have one attached to my trailer to organize the lights and I will be attaching a second one to my truck to make adding extra wires easier. They are marked with the 7-pin wiring standard. (Here's the trick, there isn't a single 7-pin standard (EVEN in the US)) They're big enough to handle multiple wires and connect to one pole, and the box is big enough to hold the wiring. Cons: They're not waterproof, water resistant, yes. So plan accordingly. If you are connecting a 6 pin or 4 pin trailer or if your trailer meets an alternative standard. You need some WORK. If you buy this product, you MUST! Basic knowledge of electrical installation and electrical engineering. No, you don't need to be an expert, but if you don't know how to use a multimeter, schedule some time on YouTube or elsewhere to learn the basics. For the price I would highly recommend these, they work well. I bought two and am very happy with both.
