Jim, this is what I have presently:
Pin 50 has 0 on it when the car is running.
Pin 31 reads 18 ohms, set on a scale of max 2K. I also checked all the there ground wires (metal loops) which connect at the head, above the AIC valve...since Bentley says these grounds are used for the Throttle position sensor. I also checked the throttle angle transmitter (203 Bentley) and as near as I can tell, it has contacts which close when (1) the throttle is closed, and (2) when the throttle is wide open. These 2 positions were the only way I could get continuity thru the 3 pins.
Any other thoughts ? I have not ruled out running an idiot switch into the cabin, jumpering straight across 12v to pins 87 & 87B to get some AC!
