For future reference, I believe the wire for the clutch switch is the red wire/pin 41 on the ecu (on a 97 M/T at least). I will respond back to confirm this. I do have one question though. Here's the message I got from their customer support regarding the clutch switch:

"Hi,

You want to splice into the cruise control clutch switch. It will be the clutch switch that changes with a small amount of pedal travel. It can be either a ground or 12v. It just needs to reliably change from 12V to 0V or 0V to 12V when the pedal is pressed. If it is backwards, you can change it in our software."

Now based on this, the voltage should change when the pedal is pressed. My question is, when I'm driving with my cruise on in second gear going 30mph, if I push the clutch in and shift into third gear fast enough, my cruise control never shuts off. Now, if I just push the clutch in and hold it, the rpm will rev a little and the cruise will shut off. If this "clutch switch" was working correctly, shouldn't it shut off the cruise the moment I push in the clutch and sees 12v? Or am I failing to understand something? My wife's car is a M/T and as soon as you begin to push in the clutch, the cruise will shut off instantly. Any ideas?
