Trailer Breakaway System, Coiled Cable Switch, LED Indicator, 12V Battery Box with Charger, Used for Electric Braking System

This thing is built better than my wife’s fake boobs and I like her boobs a lot.

it applies the brakes when trailer brakes away

Just need to add what the PURPLE WIRE IS FOR?Nice design, like the one cable with the plug, like the LI battery, just need to add direction for purple wire.Emailed the seller, no answer still.I’ll update if I hear from seller so y’all will know what to do with the PURPLE WIRE.

Seems to be a nice unit for the price point. I like the test light for the batteries. I know I wasn’t paying a lot for this but there was some issues. There was a screw on the inside loose and rattling around the case. And the port has an oring on the outside of the case that was pinched and came off. So replace oring and put silicone to seal it. When talk f the case apart to find the rattle there is no seal behind the case and lid. So siliconed that before reassembling the unit. The loose screw was a clamp for the port to the out side. Not really a big deal. If I buy this again I would disassemble the unit and seal it since they are out side.

Simple to install and works like a champ. Very affordable.

Office small battery. I hope it has enough power to apply the brakes. I haven't tested it yet. The cord is very high quality to connect everything too, but the box is rather large bigger than the frame of my trailer. But at least it's legal now

Came with 4 wires not 3 . Not sure where purple wire is supposed to connect to. Instructions not that great.
