Has anyone used a clutch pedal switch for launch control and/or flatshifting functions? I want to install a clutch switch but I'm not sure where the best location will be. I've been doing some reading on various websites and some people are saying that it should be near the engagement point so that when you quickly let off the clutch it will turn off the launch control just as the clutch grabs. I don't have a clutch switch at all so I'll to need to make a bracket anyway. Just wondering what others have experienced. Any info/pics would be appreciated.

Thanks!
