Title: Reverse functioning IAC
Post by: Overlook68 on June 04, 2020, 03:42:49 AM
360 Magnum crate engine has a Mopar MPFI kit on a M1 intake and a 4bbl throttle body.  It's basically a 2000 era model fuel injection system that Mopar created to function for crate engines.   The IAC opens up when it should close down and slow the idle speed.  Either the prior owner changed the pins on the connection or the factory miswired the kit.     The IAC has two motor stepper.  So I assume I just need to change / swap the motor function. 

Could anybody offer any advice or wiring diagram?   This is a four pin IAC plug and I think each motor has a specific feed side and control side.  So its not as simple as a positive side and negative side.
