Dan,
I was wondering, what oil sending sensor, you use? I have heard that the 88 Fiero oil sensor is the correct one to use.
But, I have also been told, that the others sensors are O.K. to use, as well. Are the connectors the same, on all years?

If I may give my input. The 88 Fiero sensor gives the best fit and will drive the 85-87 gauges.. However, that style sensor was made in two different resistance ranges ( as it was used on many GM cars) and if its not AC Delco specific to an 88 chances are that the one that you buy locally may or may not work. I purchased one locally and had to add a 300 ohm parallel resistance to calibrate it so it would work correctly. You''ll know if you have the right sensor right away as the wrong one will peg your gauge.

Thanks! I will keep that in mind, when I go get my oil sensor, Tomorrow. Do you know if all year Fieros have the same connectors?

The 88's got a different oil pressure sensor with a different mstyle connector which is the same style as the newer cars.
You will need to replace this connector to use the 88 sensor also because most 3800's only have a two pin sensor and you need the three pin one.
If you can not find a new connector some where the ones from the Astro vans are the same and are easy to come by.
You can wire in and run the older style sensor but the newer ones work and fit better and are less prone to leaking. Dan

On the oil pressure sender connector, there is A,B,C,D. Which ones go where for the computer and chassis ground? Looks to me as if A,C and D are where the wires are on the 88 sender connector. My wire colors are all three the same color, I guess its been replaced with a different connector.

If you have the three pin connector with the proper colours the black/white is ground the tan/black straight across from it goes to the PCM and the other tan on top goes to the gauge. Main thing is the two straight across from each other is ground and PCM where the one above goes to the gauge.
With the van connector the orange is grounded, the gray to the PCM and again the tan on top goes to the gauge. Dan
