Im starting to wire up my harness and im not to sure where to hook up the brake signal wire on the 5.3 harness. Theres a wire on the proportion valve and theres a switch on the pedal with a white and orange wire. Also what does the vacuum hose on the brake pedal switch go to do I have to hook it back up. What type of signal is the 5.3 computer looking for, positive or negative
