Ok folks, I *think* the gauge is all set but I'm not sure what the correct readings are even despite the recent discussion.
I cleaned and pried apart the little plastic part that holds the connector pin that makes contact between the wire and the sensor. I cut and re-stripped the end of the wire, wrapped it around the pin and closed up the housing (I did this twice...wasn't sure the first time "held") and pushed it back onto the sensor.
With the key out and car off, gauge now reads "0" (though sometimes I have to tap the cluster to get it to drop) and as soon as key is in the first position it pegs up beyond the "3".
It stays there the entire time I'm driving and doesn't move (I tapped to make sure), even at "hot idle" if hot is around 80-85c.
When I turn off the car, needle drops to "0"...though as I said sometimes it sticks and a tap will drop it.
Is this a fairly normal oil pressure reading? Can I test this?
Thanks!

While after the hazard, I hope to check and dig around in the wiring behind the console in hopes of finding gremmies.
