What does this hook up to?

I'm not really sure what was once on here. Could it be my oil pressure gauge because now my gauge isn't reading at all it is just on low at the bottom. Here is a picture of it:

Here is an idea of where it is located. It is right under the hose:

That is the coolant temp sensor for the ECU

That is a 1g sensor, it will not be used on your 2g so it doesn't plug in anywhere. No harm is done by leaving it in there.

ECU Temp sensor. Will run like ass unplugged! edit: 2g need not apply.

Like mentioned, it's a 1g ecu coolant temp sensor, it does nothing for a 2g.

Okay. Thank you guys. So where does my oil pressure gauge hook up to then. Mine is not working and it did before so something had to have come unplugged.

You're oil pressure sender is down on the oil filter housing. It should be here.
