It was probably one of the post 73 MY 2.0's that came with the OT/Fuel combo gauge & no console, which a PO added (or visa versa).
If I were you, I'd hook up the dash combo OT gauge & use that, pull the center console OT gauge &
save it in storage, then replace it with an Oil Pressure gauge, adding the necessary sender & wiring.
That way you can monitor both oil temp & pressure.
PS - That will be less costly than converting the combo gauge, which are rather rare & worth some bucks, as are the 3 original center console gauges.
