IACV Plug... What's actually needed? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So in my harness simplification process I've pretty much got everything figured out(I think), but am unsure about the IACV plug. It has four wires going into it.

I've come to the conclusion that I *should* only need two of these four. The light blue wire(signal) and the black/yellow wire(power). Am I right on this? The other two wires seem to be part of the AC. The other two wires are blue/green and blue/red.

Can anyone confirm?

TIA.

From my understanding you only need the 2 wires + and - to pulse it on and off. The other wires list as going to the ac compressor, probably for a secondary position in the AAC when the A/C is switched on.

So if you are not using A/C then You could probably drop those.
