>Okay, okay... so it was a dumb question.  And actually I did know the oil
pressure gauge is mechanical - I pulled the hose off myself when taking the
dash apart. I just kinda... well... forgot.

So what is the "oil pressure switch" doing on my engine?  And why are there
three wires hanging near it?  Should one of them be connected to it?

Please disregard my previous response.

Oil warning light and anti-run-on valve.
