*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?

Ok, I looked down the harness from the injector wires and I found where that and the wires that go over the head merge. I saw that there were 2 clipped wires. One was red and the other looked light yellow, but that could hace been because it was a dirty white wire. Is that it or might that be the O2 sensor wires because that isnt wired up either.

New question. Can the car run correctly withough the IACV connected? I'm thinking it never was. I was looking at the coolant lines and theres two at the bottom. I'm guessing one is the feed and one is the return. I found that one of the other coolant lines had a metal tube fixed to it. Was that the way it was run before with the coolant lines connected to that tube bypassing the IACV and the people that put it back together just put it back to the way it should be?

Well, I tried the fitv blocking/coolant routing method. Nothing happend so the problem has to be the fact I cant find the wires/plug for the IACV. Can anyone tell me where to find it on the harness? I think I'm going to have to splice in some new wiring for it.

Re: (H22A1CivicEG)
Those two wires are for the IACV the blue with a yellow stripe and the red one which I think should have a black stripe I'd have to check to be sure I don't understand your coolant lines question but if they are hooked up to the IACV thne it should be good now just extend the two wires you can use the IACV plug from your civic if you'd like it's the same plug so are coolant temp switches and ECT's IAT's and other stuff so just get anyone make sure that you solder the connections so you don't have trouble in the future
