*Wiring Question*
Alright, my car (92 eg h22 swap)overheated real bad and I had to get my head milled so in the process I had them install my JUN head package. Ever since then it's had the famous jumpy idle from 1500-1600. Long story short I overlooked the fact the IACV wasnt plugged in and I cant find the wires or the plug. Where does the wires or plug come out of the wiring harness so I can find it. Also, If I cant find it would it be possible to create it?

Re: (H22A1CivicEG)
should be a round 2 pin plug with a blue/yellow and yellow/blk wire coming out of it. If you started with a civic harness, i should come straight out of the main harness. If you used an integra harness, it should be with the MAP, and TPS wiring.

It is a civic harness i'm pretty sure. And I know it's a p28. Where on the ECU do those wires come from? I'm just going to pull those and re-run them. Also, what color is the O2 wires?

IAC valve plugs into the ecu at A9. O2 wires that run to the ecu are Orange/black, which is O2 heater and goes to A6. and the white wire goes to D14. Green/white wire is sensor ground, and Yellow/black is 12v ignition.

Alright I found a9 on my ecu and the wire is green/white. The 2 wires that are clipped are red and looks like white/green. Are those the 2 wires I need for the IACV? If so, where would I get the plug for it?

Re: (H22A1CivicEG)
yes the green/white wire coming out of A9 is the correct IACv wire. it turns form blue/yellow to green/white at the driverside shocktower connector. the IAC valve sensor connector is the round 2 pin plug/connector. its the same as IAB, IAT, ECT,knock, Vtec pressure, fan switch ect.. The 2 wires that are clipped are those on the engine harness? Red/yellow and Green/white is IAT.

Where is an easy spot down the harness where I can find the IACV wires? And from there I can just run wire to the IACV and splice in the plug right? Also, which civic plug do I not need for the swap so I can use it for the IACV?

Ok, there's one wire coming from the ECU pin A9 and that wire is green/white for the IACV. I know at some point it turns into 2 wires. Where on the harness would I be able to find the 2 wires easily? I'm going to cut the wires there and splice in some new wire to a plug and get this idle problem out of the way. Been plagued with it for a while. Any help would be much appreciated. Thanks in advance

on the eg harness: plug1, (blue with yellow stripe, and light yellow with black stripe)
IACV is what turbogixxer gave me i cant say thanks enough to him.
here is a pic.... and you can see the blue wire on the harness my buddy bjorn is holding up. the wires should be next to your injector plugs.
hope it helps.
