Wiring Harness Question

[BMFBUICK]

Here's my question found a small gray plug with single green wire disconnected and hanging not sure where it plugs into. It's coming from the area in front of the throttle body. Any idea's what this may plug into? Thanks for any feedback.

Does your car have an aftermarket water temp gauge in it? That wire sounds like the wire for the factory idiot light. Most people I have seen replace the idiot light switch with the aftermarket gauge's sensor.

I do have an aftermarket water temp gauge, that was installed years ago. Thanks for such a quick reply!

No problem. That plug is flat, right?

Yes it is flat. My car has been sitting several years after rebuilding motor. I'm sure I will have more questions later. I have only put a 1000 miles on it in the last 9 years. Got married had kids and no time to play with my car. Finally up and running thanks for all your help.
