There is a three wire sensor on the other side of the motor that CAT supplies for the ECM.
I do have a oil pressure light that I see when the key is in the run position. I am sure that this is what this switch is providing.
There must be another sensor somewhere else that provides input for the oil pressure gauge itself.
I have ordered a 15psi switch to replace the leaking one.
