What is the model number of your Autometer pressure gauge?
Is your original pressure sensor a pressure switch (fault light) or pressure sender (pressure gauge) or both.

Oil pressure gauge types:

Mechanical with [/s]filled gas tube[s] oil filled tube.
Electrical switch (on/off)
Electrical pressure (analog)
Electrical digital (digital communication with the gauge)
Electrical digital computer bus (digital but shares a bus system to talk to a central computer)

We have to figure out what you have before we can try to recommend what you need.
