I have a MF35 diesel with thermostart(intake manifold heater). The original switch was not wired and does not work. I got a new switch that has the same terminals but I don't know how to wire it. There is a position for off, start, heat, and heat start. However there are only three terminals. One terminal has two prongs. How do I wire this? Where does the feed from the ammeter go?
