Oil Pressure Gauge?

[982dr]

I used the gen 3 sensor and it feeds the ecm and the gauges in my truck...why run two sensors?

EDIT: I did swap to 95+dash and gauges as well..

Just to clarify: The gen 3 oil pressure sensor will give the correct signal for the OBS gauge? And did you splice the OBS gauge wire inline with the gen 3 wire to the ecm?
