Is there an Oil Pressure and Water Temp. output signal on 95 LT1 PCM ?

So the LT1 Camaro's, Caprice and Impala's did not have factory oil pressure gauges but my little V6 S10blazer had one. That's Odd.

I think you confused oil pressure switch and oil pressure sensor in my previous post. The F-body LT1's did not have an oil pressure switch. They did have an oil pressure sensor. It looks like that switch/sensor combo you have but it only has the middle pin where you are missing the wire. There is no switch in it.

FYI, you can also get one that has the outside 2 terminals and is only the switch. You got lucky you used the 3 terminal one that you need to get the gauge working. Good luck finding the terminal and wire.

You could use the 3-terminal unit to replace either of the other 2 units. You can not use one of the other units to replace any of the other ones though.
