Have an opportunity on an upgrad to a IC but before sinking money into the upgrade, I need to know if the Ic will drive a 4 wire GM IAC. The wiring connection diagrams (pinouts) do not show the 4 wires needed for a IAC. I use a 4 wire IAC now and know how to set one up and wouldn't run without it. Can the capability of the IC handle it and where can I find firm information on this?
