This is a sturdy quality kit for the price. Easy to put together and worked perfectly to replace my old 7 pin. I saw some reviews about some people complaining that this junction box doesn’t come with electrical connectors. Let’s face it if you don’t have electrical connectors in your garage then you’ve got bigger problems lol.Anyways. Good quality junction box. Sturdy wiring.

Worked perfect for our vintage Trailer wiring upgrade- Nice and Neat and Accessible- Color Coded, easy to install ( we did install ring terminal connectors on our wiring ) for ease and a better connection to box)

It's a little on the light-duty side - wire gauges are in the 14ga range, would have liked to see them closer to a 10ga size. But will work for what i needed it for, which was a budget rewire on a trailer that will only see a few hundred miles a year.

Purchased as an inexpensive replacement for my aged and damaged trailer harness, I mounted the junction box in frame just under trailer decking, worked great for rewiring to existing setup.

The molded plug is not wired correctly so it took me 2 hours to diagnose and trace wires to figure out what color wire did what. How hard is it to follow an international color standard? I also assumed the 4' was the cord length. It is about 47" from the very tip of the plug to the very end of the control box. Who measures it that way?

Bought this as part of a rehab on a 16 ft utility trailer. Plenty of room in the junction box to connect the wiring. Clean and easy installation.
