Expert Reply:
I do not have any information about which particular wire you are looking for, but I can tell you how to find it.
Simply use a circuit tester like part # PTW2993 and probe each of the four wires until you locate the wire that only shows voltage when the brake pedal is pushed. This will be the circuit to tap that red wire into.
