I do know the C5 TB polarity is reversed from the Truck TB, as I tried using it ultimately at first with the C5 TAC. It would respond, but REP... ultimately swapped all throttle hardware over from C5 parts. Wish Id spent more time on this, I know it could have been useful to get that enabled to someone..
