Expert Reply:

There's a short between the stoplight circuit (red wire) of your brake controller and the 12 volt power wire (black wire) which is tricking the controller into thinking the brakes are applied. Go through and insulate the wiring better with electrical tape like # PTW502 where the connections are made and the issue will go away.
