For brake controllers like your Hayes Lemmerz Energize III part # HA81742B the white wire gets grounded, the black wire runs to a constant 12 volt power source, the red to a wire that only has voltage when brakes are applied (normally on the brake pedal switch), and the blue to the output circuit of the 7-way connector.
