I didn't find another wire on the oil filter housing so Still looking for the oil temperature gauge sensor. Didn't have much luck tracing the wires from the rear of the dash gauge.
Can anyone ID the white wire at the lower centre of this photo?
That cerainly looks like the fuel solenoid on the pump.
Start her up and pull it off, and if the engine stops, that's what it is
The temp sender could be blanked off as it's adjacent to the pressure switch.
