Brake switch wiring?
I have some troubles with my brake switch wiring..
I have just finished a TPI swap to my 87 Camaro.
Now it is a 305 TPI engine (MAF System)
I need some information about the brake switch cables.
On the brake switch there are one purple cable and one Pink/black cable.
The purple cable goes under the dash over to the passanger side to the C207 connector. But the problem there is that there is no purple cable on the TPI wiring harness..In other words that cable is going to nothing. Just free air.
I think it is on the "P" port on the C207 connector.
And I don't know where the other cable is going. The pink/black one..
The only thing I know is that there is 12V on the cable when ignition is On so I guess this is a power source or something??
Pleace help me out here...

Re: Brake switch wiring?
those two wires are for the TCC (torque converter clutch). pink/black sends b+ to the purple wire when brakes are applied to let the trans know the brake is being applied and to realease the tcc.
