Ok so here's the situation
90 ls swap into a 90 SI crx
Si Wiring harness on the b18 motor

Missing a connector for the iacv Not just a connector but the whole wire too
Harness was not hacked the wire to hook up the iacv simply is not there.
I'm not sure what to do. but need some help.

I'm looking at the harness and there is a connector for something that was not on the B18 Intake manifold Small two pronged connector with a solid blue wire coming out of it and a black with yellow wire

 

bump

 

are you talking about the iacv on the back of the manifold or on the side under
the throttle body? you have to retain the one on the back but the one under the throttle body can be inoperable and the engine will still run. you might have some problems
getting the car to idle easily but it will not hurt your engine. i have a b16 with an aftermarket manifold that doesnt even have a place for the iacv on the side and the
only thing i have a problem with is the idle.

 

The one on the back is what I was talking about. The bottom one is hooked up but the one on the back is not. I'll give it a shot. sweet thanks
