I want to gawk at Mikes shop, not work in it. :elkgrin:
Thats not how it works... I doubt that is what the box is. Does your trailer have a breakaway system? They usually have a battery, and a small pull out switch deal if the trailer should come unhooked, the battery sends full 12 volts to the brakes and locks them up.
The controller has to be inside the vehicle. The electric brakes on a trailer are pretty simple, and use a magnet/coil to control the shoe movement with a single input DC signal. And of course a ground wire. Thats it. Nothing else to the brakes on the trailer side. The heart of it all working is in the controller, which is inside the tow vehicle. Most controllers also have an emergency way of applying full stopping force (or a preset amount of force)to the trailer without pressing the brake pedal (usually a slide switch)
Some brake controllers are time delayed, and some are proportional. They both are very adjustable as far as how quickly they apply full braking force, and how much force to apply based on the weight of the trailer. You usually set the gain as high as possible up to the point before the wheels lock up.
Trust me, you dont have a controller under the trailer.
Have you decided which controller to get yet?
Here is a great info article on brake systems, it also shows a wiring diagram (you will appreciate just how simple it is...)
