Re: disabled oil injection
I'm not familiar with oil injection systems and I don't know the circuitry, but the easy answer is to find out what state the wires are in (12V,GND,other...) and hard wire them to that state. This info could possibly be found in users manual. Chances are the (the low oil sensor) wires make continuity through the oil in the tank and when it falls below the level it opens the circuit. My guess would be to just leave the overheat circuit in operation.
