I see by the first picture that you have an aftermarket air intake, I believe that what you are missing is on your factory intake.

Can anyone just look under the hood and help this guy? It's a very simple process instead of telling him to buy the manual.:hithead:

If I still had my DA, I would tell you. Be careful because theres some coolant line that runs from the Intake Manifold. I can't remember which one it is.

That connector is for your EGR valve. It reports back to the ECU whether it is working or not. The plug you are looking for is usually attached to a metal bracket directly below and to the left of the EGR valve itself. Regardless, you are looking for the connection to be somewhere down there, running to the main wiring bundle. That wiring bundle has a ground connection to the thermostat housing as well. You might have to move the intake hose to look around for it, maybe it is dangling down below...

Just curious.. what year is this car?

I have a 93 engine and a '94 engine, and both engines have different intake manifolds then you. Slightly anyways.
