IAC pinout Does anyone know the pinout for the IAC valve on a 2K Formula? I came across a troubleshooting suggestion where it tells me to apply battery voltage between signals B+ and -Na then -Nb. The diagram in this guide shows a 3 pin connector but the one I have in my hand is a 4 pin.
I'm sure the service manual shows it but I don't have it here at work. I want to connect a variable power supply across the correct terminals and observe the pintle's movement. I'd really appreciate some help. Thanks.

I've heard that energizing the IAC when it is out of the T/B will shoot the pintle out of it.

Better not mess with it Thanks man. Yeah I'm not sure I want to experiment with this one. $175. to replace it. The one in the troubleshooting guide shows one that looks more like a solenoid anyway. Our's uses a stepper motor and I don't think applying 12 volts to it would be a good idea. I wish I had a known good one to swap in.
