I purchased a Haltech IAC valve (4 wires) to use it for Idle control of my Evo IX.
My TB is the classic Q45 and my intake manifold is HKS Kansai.
I will try to bypass air through the TB to control and improve the idle of my Evo IX.
The hardware is ready except the wiring harness!
The OEM socket of the OEM IAC valve has 6 wires,4 that is AUX 5-8 and 2 other that I do not know what???
The haltech connector has ABCD marks on it.
Which one from the Haltech wire harness to which one of the M800 OEM wires I have to connect and what values I have to use?
The only thing that I know for sure is that the Haltech IAC valve is 200 steps max.
