I need to know where to find this thing.

It's underneath the intake manifold, roughly level with the distributer. It's also put in at a bit of a funny angle. It's plenty easy to replace when the intake manifold is off, but virtually impossible otherwise.
You can see it here right beneath the cam cover.

If yours is an 85 or later, it should be larger than that one. That one appears to be an 84 motor that only had an idiot light and no guage. The later ones are shaped somewhat like a black bulb.

I have never seen an 85 with a light for oil pressure. The standard 85 instrument panel has an oil pressure guage in the lower portion of the tach. Are you sure someone didn't put an 84 guage cluster in? If you do have only a light then you will need the smaller sending unit.. It's simple to take it off. Pinch the wiring plug on the top, pull it off and find a wrench that fits the nut on the bottom of the sender just above the threads and take it out. Put the new one back in the same way. You may have to work by feel some because of the location it's hard to see it.

Nevermind, I must be on crack or something There is a guage there.
Is there no way to tap my newly purchased oil pressure guage into wires that go to that guage? now knowing that I do have the stock oil pressure guage, how do I go about remove the stock O.P sensor?
My 88 duke had the newist sensor, so your experience will be a little diferent. O'Rileys had a rental socket that is used in conjunction with the replacement sender that they sold me. The socket didn't fit the sensor that was on the engine, but since I knew the sender did not work with the guage, I just used a crecent wrench to remove the original sender. I had just enough room to work blind from above/around Intake manifold. I didn't try from below. It took a little while to get the new sender 'stabed' in but it was do-able.
Sorry I don't know the pin out for the plugs, I have the 88 Pontiac shop manual, and can find what the wires go to for an 88. I don't know if the electricals changed on that circuit between 85-88. Did you get the 88 style sender and need to adapt to an 85 plug and wiring?

The tan (maybe tan w\black stripe) should feed the guage. There is also a +12V line and a FP line going to that sensor. The sensor by-passes the fuel pump relay once it sees ~4PSI oil pressure, as a redundant backup to the relay. So dont fudge with the other wires. Though seems to me you'd be just as good using the stock guage, since unless you had a mechanical oil pressure guage, the accuracy will be generaly about the same as the stock guage, which is more than adequate for daily drivers.
see here's the thing. I bought a A-Pillar guage pod that holds 2 guages. I got it because I always liked that look.
When I asked people what guage I should put in there, most people said the oil pressure guage. One of the guages I have in there is a Voltage guage so I can moitor my voltage when I have my stereo cranked up. I just needed one more guage. I am begining to find that maybe the oil pressure guage is not the best choice. But I don't know what else to put there. Not having the guage pot there is NOT an option.
Any ideas.
