I second that this is an important upgrade you can do on a trailer. I did the same upgrade about a month back. I had plans to replace the box, but started having random loss of brakes before. Luckily my truck doesn't have a problem stopping the trailer on its own. I traced the problem back to the 7 pin junction box. I did a lot of traveling up north this winter on salted roads. The wire nut connections were all wrapped in electrical tape, but all of them had begun to rust. The nut for the ground connections was rust welded and took quite a bit of effort to snap off. This was on a trailer that left the factory floor just 5 months prior. I ended up replacing the whole box, replaced wire nuts for ring connectors, and heat shrinked the connectors. While I was there I went ahead and upgraded the brake wiring and connectors to 10 AWG.
I'm not sure why the industry still thinks that a junction box that's meant to dry locations in a home would be appropriate to install on the exterior of a trailer and at a pretty low point at that. They could at least us waterproof connections inside of the box.
This is the box that I used. It's a little cheaper and the studs are built in. However there's a tradeoff. It gets a little cramped in there because of the size and there's no room to include other items in the future. Good for those who are watching those pennies though. If I need to add more items then I'll move up to a box like yours.
