the tcc wire gets power from the brake switch. The brake switch is a special two terminal switch. Four single wires. The first two are for brake lights so you have constant power to the brake switch so when you apply the brakes the power goes to the brake lights, Tcc wire are on the top of the switch. It works just the opposite. Power is suplied all the time from a constant power source to the tcc wire. When you apply the brakes it disconnects the power to the trans convertor.
