Just saw your post on LS1Tech and figured it would be easier to get in touch on here and saw this post. Anyway, basically on a GenIV swap, you just have to hook the TCC wire to the brake switch so that it has power when the brakes are APPLIED, the opposite of the older engines. So just test the two wires on the brake switch, one will be hot all the time and the other will be hot when you press the brake pedal, hook it to that wire, the same wire that supplies power to the brake lights.
