Ok, here is one to rack your brains on...

I just purchased a TraqMate data logger system with the accessory input module. I would like to hook up RPM, Throttle Position, Brake (on/off) and air/fuel. The system has a trigger input for RPM and analog voltage measuring inputs for the others. They can be set to 0-5, 0-10 or 0-20 volts DC. My question is where to get the signals. I heard there is a pin on the OBD-II connector for the RPM, but what about the others? Brakes are easy by using the brake light, but is there an easy place in the cockpit to tap into it? Throttle and mixture are the two that I have no good idea where to start. I don't want to fry my computer so I am not keen on guessing. Anyone have info?

Ed - did you ever get an answer to this? I think the ECU wiring harness is beneath the rear (on 996 at least). I didn't notice whether you had one at WGI this weekend.
