Very nice! Keeps wiring organized.
This is my first trailer project and I appreciated how the wiring installation was clear. After a trial-and-error learning curve on my part, all my lights work and the brakes as well. First picture is about halfway through the wiring process. In the end, I attached a solid ground to the trailer and white post in the junction box, and used split wire loom tubing to cover the wire. It came out looking professional in the end.

Good Quality and Value
Good quality kit with a clear set of instructions explaining the differences between the wiring systems on RVs and trailers. Made it very easy to fit and wire into my trailer lights. Exactly what I needed and a very satisfied customer. Very good value.

Easy to Install and is a quality junction box.
I found this easy to install. I has excellent documentation. I really appreciate that it has posts to connect each wire to. My old junction box just had wire nuts for connections. Highly recommended.

A must for any trailer
I have bought several of these cord/junction boxes after installing it on one trailer I’ve installed it on every trailer I own it’s the first thing I order on any trailer I buy even if I plan to sale it

Decent quality.
Good quality kit with all the pieces to install a trailer breakaway. You will need to buy separately a battery and small charger for charging the battery from the vehicle power. 2 negatives: 1. the wire appears to be aluminum coated with copper so it looks like copper. The cut ends of the wire are silver... 2. They say the cable is 8 ft long but it's 7.5. That works ok for me, but may not for everyone.
