DiscobayJoe that's one brave move ripping the dash out your Carrera! It's looking great so far. There's some bad news on the ccStick front though. Check out http://www.mp3car.com/vbulletin/input-devices/74301-ccstick-rotary-encoder.html
Have you considered the Force Feedback (Haptic) Encoder from mp3car.com?

Discobayjoe - have you had any time to document the Carnetix install? I'd love to see where you pulled the wiring for it.
