The phrase "the cold side of the brake switch" refers to the circuit at the brake switch that carries voltage only when the vehicle brakes are applied. This circuit varies widely from vehicle to vehicle so the best way we can recommend you find it is to use a circuit tester like part # PTW2993 to test the wires of your brake pedal switch till you find one that only carries voltage when the brakes are applied and none when released.
