Hey everyone, I tried looking for a topic about this but all the posts were referencing MS3s. Where would I connect a generic GM IAC (usually with 4 wires) to my ECU? I don’t see anything referring to IAC on the 26 pin connector on the manual. Thanks.

What generation of ECU do you have? On early models, you need to add wires to bring the signals from the MS2 board to pins on the output connector.
