If I'm bored later Ill look up the wiring schematic on SI and show you how and where to put a switch on the power or ground. Though I don't suggest doing it. It is much less of a hassle to learn how to drive with it on then try and disable it and have other systems run amok. Once you disable your T/C, then your CEL and T/C message will constantly display. If you have another problem you will most likely not be able to detect it, since at the first occurence of a problem when the ECU stores the code, normall the T/C service message will display. But hey, it's your car.
My turbo lag is your courtesy head start.
