Are you sure of that? How dies the low oil pressure light function without that type of information?

EDIT: The wiring diagram shows an oil pressure switch, with a GN/WT wire that feeds directly into the White plug (position 6) in the instrument cluster. Not sure if this is an on/off voltage or if voltage is related to oil pressure in a linear fashion that could be used with traqmate. It would be easy enough to put a meter to it and rev the engine to see if there is a voltage increase with increased oil pressure.
