What Cars had L36 and Oil Pressure Gauge?

According to Rockauto, the oil pressure switch for the 2000+ Bonneville also cross references with:

Now, depending on what year harness you have, maybe you need a switch from an older 3800:

And I'm sure you can find a cross reference for a 3800 oil pressure switch from a mid to late 90's vehicle also, that also swaps over from anything and everything GM.

 

 

So yeah, as I suspected, they are pretty much swappable all over the place.

Well, the 3800 is out a 99 lumina, so I'm thinking that if I ask for one from a 99 Bonneville I should be set? The 3.1 oil pressure sensor is variable resistance that 0 ohms = o PSI, and 87 ohms = 80 PSI. I would think they should be the same given that they cross-referenced all over the place? Does that sound right?

Probably so, or maybe you have that backwards. If you have one sitting on the shelf, try it out.

 

I don't. That's the problem, I'll need to buy one, so I'm hoping to get the right one. If I could see the wiring diagram for the 99 Bonneville or any other on that list I could figure it out. Anyone know where I can find the diagram for the oil pressure sensor?

So I found a diagram for the wiring and it looks like the 3800s ran significantly higher oil pressure, but use the same theory for the sensor. On the 99 Bonneville 0 PSI = 0 Ohms, but 120 PSI = 90 Ohms. So the sensor itself will work and function, but the actual PSI the guage on the TGP reads will be off to what the engine really has. Maybe I'll swap in a Instrument Cluster for one that doesn't have numbers. So I'm going to try that, just thought I'd post what I found.
