I am looking for information, schematics, or links on how to install electric brakes on my trailer. Not the controller in the truck, but the brakes to the trailer. It is an '83 Hartman dual axle two horse bumper pull if that matters. Any information will be greatly appreciated. Thanks

A couple of generalisations;
Brake magnets typically draw 3 amps each.
They are wired in parallel, so be sure your wiring is adequate for at least 12 amps.
Ground (return) seems to vary, you may have a short ground wire with a terminal already crimped on it that is to be put on an existing stud that is a good ground.
Alternatively, you may have to connect all the grounds and run them together back to the trailer's ground plug. Again, 3 amps each or 12 for the set.
This is likely to draw some disagreement;
Avoid soldering terminals onto the ends of wires, or soldering wires together.
The solder wicks up the wire, which then becomes rigid (though "strong"), it will break instead of bending.
Use crimps ONLY !
As I said, "likely to draw some disagreement" (-:

I like solder joints. Here's why:
You are correct that a solder joint becomes rigid. But so is the crimp. Both types of connection will cause wire flex beyond the joint. The solution is to mechanically support all joints. Don't leave the connection hanging by the wires. A solder joint has the advantage of corrosion resistance. Only the crimps and wire nuts with the wire sealant are better for ease of application.
