I do have a solution for you but unfortunately, I don't have information as to the location of the blue brake output signal wire on a 2002 GMC 6500. I called a very popular trailer brake controller manufacturer Tekonsha, and they were also not able to provide this information. Your best option to install a brake controller on the vehicle would be to just run a new wire part # 10-1-1 (per foot) from the brake controller to the 7-way. If the vehicle did not come with a factory 7-way then this wire would also not be present and you would need to use part # ETBC7 to install a brake controller.

For charging a trailer battery you want to go with as thick of wire as you can. 10 gauge would be ideal. We sell 10 gauge wire by the foot with part #10-1-1. Typically a 40 amp breaker like part #9510 is used.

It has to be the ground then of the brake magnets. If they are all getting voltage and not applying the problem is the grounds. Make sure the magnets are connected to a clean portion of the trailer frame or you can run ground wires from each magnet…

You should be able to ground the brake magnets to the frame of the trailer and have them work fine. Or you can try running a jumper wire back from the ground wire of the magnet back to the main ground of the trailer frame. If you are getting 12 volts…
