yeah I see there is a wiring harness right next to the clutch. It would be easy to tap into that with a seperate relay and switch. I just read this thread about LET doing a TT setup for the C32

If they are able to force the turbocharged air passed the disengaged SC then that might inspire me to pursue a rear mounted turbo setup. I would think to bypass the SC clutch you could just pull the plug and if need be possibly place a resistor across the terminals to trick the ECU?
