Alright Opponauts, I’m putting a bounty out. 1993 Camaro Z28 IAC 4-pin connector. Square plug - NOT FLAT. Two green wires with white stripes, two green wires with black stripes. I understand that black is LO and white is HI, but how do I determine which is coil A and which is coil B? The bounty is fifteen-hundred internets.

The plug is disintegrated. There is no way for me to deduce, via placement or otherwise, the original wire order.
