OK, got an L36? You can help. My L67 swap is using a L36 harness adapted over. I need a plug IDed however. I believe I don't need it, but confirmation would help.

On the rear, under the engine cover is a two-prong plug. It emerges right before the front O2 sensor plug and is gray if you unplug it. Wires appear to be orange and pink/black if I remember right.

I think it runs to some sort of AIR injector or EVAP solenoid that isn't used on an L67. Let me know what you find.
