Hardy,
Its 12v+ 10amp from the fuse box via C1 connector. The switch is normally open then closed when brakes are applied.

I was thinking of the neural safety switch on a 4l60 it provides a ground. Sorry for confusion!

hardy what that wire needs is +12v when brakes are not applied and whenever you step on the brakes power needs to be cut off,, the way I did mine, just go to your local parts store and order the brake switch for a camaro or trans am.. this have the normal plug for the wires for the brakes and another outlet for that you can plug prong to a +12v source and the other to the tcc wire for the pcm... hopes this helps

dr461 is the brake switch part number at autozone 5.99
