What is this for?

So I noticed the screw holding this wire in must of fallen out. Anyway what is it for? I'm thinking oil light? (It was on, but now off) one last question anyone know what size screw goes in there?

Looks aftermarket, but I'd say that is your oil pressure sending unit.

That for the oil pressure light. From the factory there is a flat male connector that is held on by the screw and the female connector on the wire slides over it. I would only be guessing, but i am thinking that the screw is a m5x.8 .

Oil pressure sending unit?..If it fell off then where is the oil leak?..

Lol, no leak... it simply just sends the electronic pulse to the ecu to notify you if the oil pressure/amount is too low. The bolt bolts into the dummy light switch which actually bolts into the Oil Filter Housing. No oil will leak from this bolt location. Suprising something that won't leak on this car!!!

In the picture attach the black circle to the greean circle with the M5x.8 smallest length bolt. Done!

well knowing my oil pressure was good i started the car, and the light was off before i put the bolt in...... did it maybe touch somehow and blow a fuse or something? I did re install the bolt but just curious if for some reason i may have burnt the bulb or if there a fuse, that caused the light to not come on when it wasn't re attached? I want the dummy light to work obviously.
