IACV Tech help please!

[supradealz]

Have horrible idle cold and hot. Stumbling like crazy unless at medium to WOT. PCV valve works, cleaned out MAF. Culprit is probably IACV. Didn't see any loose vac hoses.Pulled the IACV (I think its the IACV, it says AAC on the part) but I'm confused with the FSM. On the S14 KA24DE manual its showing 2 pins for diagnosis. I have 4 pins. On the S14 SR20 FSM it shows 8 pins.I want to check the wiring on the harness and also check the IACV. Any suggestions?I metered the harness and I'm getting 12v switched on the 3rd connector (c).
