Sorry we seem to have hijacked the oil pressure sender thread.
I would think that any oil pressure sender has to have a three wire system to give an accurate pressure reading.
A two wire pressure element would just be a light indicating low pressure.

Unless it’s a specific resistance in the meter movement circuit. Like an RTD in temperature circuits.
Not common theses days.
