On the Camaro, you could reverse the switch so that off was the default setting and turned it on to engage it. It wasn't a difficult mod since there were only 2 choices, TC on or TC off. With the vette, it is more than on/off since you have to be able to cycle through to AH. If you're good with switches and relays, maybe you can figure a way to rewire it.
The other thing we would do at the track is physically disconnect it which took 20 seconds to do. Downside is that if you want it to work at times, you can't do it on the fly, and IIRC it generated an idiot light.
