you need to check voltage of your reverse lights coming thru the pigtail on your truck. when in reverse, you should have at least 10VDC or better going into the 3 blue wires on the trailer pigtail. one of the blue wires goes to the brake actuator like nj skier says, the other two go to each reverse light. when the actator gets the correct voltage signal, it will disengage your brakes so you can reverse without the brake pressure. get a voltage meter, a friend to help you keep the truck running and in reverse with brakes on (for safety reasons). i had a slight grounding problem on my truck and wasn't getting enough voltage to the actuator to fully disengage the actuator.
