(Megasquirt 2 V3.0) Hello, I am using a 3 wire Bosch IAC on a Porsche 944 S2 and I saw that in the assembly guide there are different methods of wiring the board for different IAC valves. I think that what I have is a stepper IAC. I have also found a picture on google that has the 3 wire IAC that goes
FIdle output
+12 ignition feed
Ground with a resistor

Do I go ahead and make the jumps per the instructions and then go Fidle output to the IAC?

Thank you so much, Chris

3 wire is PWM, not stepper, and wires as you described.

Okay, so it is PWM, thank you for that. So, then I should connect JS0 to IAC1A, JS1 to IAC1B, JS2 to IAC2A, and JS3 to IAC2B?

Again, thank you so much for all the help. I am super new to anything like this and I know that I bit off more than I can chew but I am excited to learn!

Thank you, Chris

Sure, I'd run the standard stepper jumpers as they can be put to other uses.
