No, it does not matter which wire from the magnet is attached to power or ground. Just make sure one wire is properly grounded and the other wire is attached to the electric brake output circuit from the trailer connector.

I have linked a video that details replacement and wiring of a trailer brake magnet that should be helpful.

You cannot really go by miles when determining when brakes should be replaced. You would know to replace them the same way you would know with a vehicle. If performance is suffering and adjusting the brakes does not help and there are no other issues…

Most if not all trailer wiring harnesses/connectors use larger wires for the 12 volt and ground circuits compared to the other circuits (lights). The sockets themselves don't have an amperage rating so you will go by the draw of the things…

Suspension hangers like what come with the Hanger Kit part #APT3HD that you referenced are designed to be welded to the trailer. You would not want to bolt this kit to the frame of your trailer.

Answer 10

To wire your electric brakes you will want to run 10 gauge wire #10-1-1 to one of the brakes and run it to the other brake, using butt connectors like #05732-2 to connect them. The grounds will not be spliced, each brake assembly should have its own…
