IACV Plug

[dAzLr]

hey guys i need to wire up the idle air control valve on my jdm b18c, its on the back of the intake manifold its only has two wires on it so im guessing one goes to the ecu then where does the other go too ? cheers

[Edgeauto]

Same power wire as the injectors

[dAzLr]

polarity concious or na ??

[Edgeauto]

Shoulnt matter but the black/blue wire is the wire that goes to A12 on the ECU

[dAzLr]

then which wire is the power for the injectors cos dont they all have seperate power sources from the ecu ??

[ECU-MAN]

yel/blk wire

its also power the Purge solenoid ( PSC )

[dAzLr]

are u sure its the 'psc' cos i cant find anything on the psc on the ecu pinout i have it only has pcs (pin A15) or is that the same thing ???

[ECU-MAN]

im not saying the connector is the PSC, Im saying that you can get power for the IACV from the injectors and the PSC, yel/blk wire.
