Thanks Fred, that's very interesting... I had success with the temperature so far. If I connect the yellow with red stripe wire, to temp, and white wire to temp ground I get an accurate temperature reading so I know that part is currently working... I'm assuming that also closes the circuit. I could just take the boat out for a run, but I can't mess with wires while driving around so I think I'm going to try pulling the sensor tonight and see how it goes. It probably needs a good inspection and cleaning anyway. I do have the necessary plug to replace it so fingers crossed - at least I'll have this experience to draw upon in the future.
