I just bought a trailer brake system and I also got the plug in adapter. I hooked a trailer up to it and every light works but the brakes. So basicaly the trailer brakes dont work. Does anyone have a clue were to start? If you have any ideas were to start it would be greatly appreciated?:help

Check and make sure controller is getting power, then if it is see if signal is getting to plug.

did you wire up the harness right to the controller? i know the wires are the same color dont go to the same color wires on the plug (that would be to easy) lol

just a thought...i've seen a few people do it. and you'll still have lights just no brakes

I bought the adaptor that connects right to the truck so i didnt wire anything. The brake contollor is getting power but were you connect the trailer to is not getting power.
i hope that makes sense.

Are the trailer brakes wired correctly? Have a friend hook up his truck and check to see if they work. That'll rule out the truck or the trailer.

Ive already done that. Does anyone know were there could be a bad connection other than were you hook the trailer up?
