H22 iacv wiring
hi all
i am trying to wire the iacv for 93 prelude h22, there are two wires. I know that one wire goes to ecu A9 and the second is power. But the problem is my wiring is hacked. How can I know which wire goes to ecu? If the wires plugged to the iacv where does the top and bottom wires goes to? I am attaching a photo

Re: H22 iacv wiring
It doesn't matter which goes where... there is no polarity on the circuit. The "ground" wire if you will goes to A9 at the ECU and the other wire will go to 12v+... any yellow black wire that has 12v+ on it when the key is on will do. There is a junction plug on the engine harness with seven or eight yellow/black wires merging into it... that is where I would go.
