In the final stage of getting my car put back together from two years ago an never labeled anything. As you can see this wire is attached just behind the oil filter (the black square plastic). I don't see anything that this connects to. Might be to something I removed since I got rid of a ton of **** but I just want to be sure what it connects to.

 

That would be the condenser for the oil pressure sender. There should be a matching plug on the harness with a yellow/red wire.

 

You say it's on the wire harness? I gotta say I don't see anything that fits that plug. Pretty frustrating cuz it looks like it would so obviously fit something too but I don't see the damn thing.

 

Should be on the engine harness I believe.

If you can't find it, it's not going to be a huge deal. Most of them have been disconnected or missing since someone removed the transmission...
