ok, i'm polishing up the wiring on my PMR, and i've got one extra plug. i always seem to have one extra plug. this is present on the stock crx si engine harness, but i have nowhere to plug it into.

things that are accounted for include the IAT, IACV, TPS, knock sensor, t-stat switch, and coolant temp. should be an easy one, but i'm being a moron for some reason.

Hard to tell but it looks like a plug that's only on the back of the stock D16a6 intake manifold (I think). I forgot what it's for.

I like the fogger set up.

Fast Idle Control Solenoid Valve. The ECU opens it if the coolant temp is below -10°C (14° F) and the engine speed is below 1,800 RPM. It was replaced by the purely mechanical Fast Idle Thermo Valve in '92.
