This is insane. I can't find anything about voltage or ohms testing the iac on this forum or any other forums. No one know how much electricity there should be. They just say. Do a search. It's out there. Well it isn't. There is 4 wires and I don't know which is which.

You need a FSM for your specific year...all schematics and diagrams with voltages will be in there. You can find them in PDF form all over the net for $10-15.

I've fully given up. Honestly. I don't care. Too much stress.
