Hi to anyone with a solution!

I would really like to find an oil pressure gauge I can wire to the standard Tan/White wire on my ECU harness bulkhead connector. I understand the required gauge should be 0-5V using this voltage pattern: (Pressure (psig) = [32*Sensor Voltage]-16). It seems like all aftermarket gauges are 12v with their own sending units. Anyone know how I can find a gauge to work with stock sender? I'm considering building my own but I can't believe there isn't one out there.

Thanks
