Was rummaging through my engine bay the other day looking at the wires going to IACV since my idle has been acting up and noticed a grey plug with 2 wires (yellow/black and red) that I cannot figure out where it goes. It is over near the IAT sensor on drivers side of intake. Anyone have any idea what this might go to? I've searched all over and have found nothing.

Any help would be extremely appreciated!

that plug is for the evap purge solenoid. since the dohc zc is a jdm motor it doesnt have one. the sensor on thew usdm motors mounts on the top rear of the intake manifold.

Thank you so much!
