The way to absolutely confirm the TC is to see whether the TC lights on the dash on start up. Here is another way. The TC is always enabled and the switch disables it. If you have no switch, the system is always on. If you try to light up the front wheels and they slip under acceleration, the TC light will turn flash on and off indicating that it is operation during that circumstance, and of course the motor will bog and stumble as the TC is operating. Good luck, it would be interesting if there are more SVT's with TC.
BTW, the TC light in my SVT was already there and working from day one.
