Two lose wires any ideas?

So i have a feeling the lower one with the spade connector is the oil pressure sensor or switch. I'm not sure which one is which though. And the other one with the small black rubber boot I have no idea.

Awesome thank you. What exactly does the PS one do ? I havent noticed any difference and I have no idea how long it's been off.

It goes to the ECU and the ECU will adjust the idle speed when it's grounded to avoid stalling.

Interesting well I have it hooked back up now.

You probably won't notice unless you're actually at idle and make a steering input.

And have a working idle control circuit. (working ISC, correctly adjusted BISS, etc)
