If your ignition switch has three positions (on, off, momentary start), the switch is the same as I posted (attaching an enlarged version.) If it's only 2 positions, it will have just the three terminals that bartamos mentioned, one battery, and two switched terminals both on at the same time. If it's three position and you have a foot start, it may just not have the start terminal wired. Hope that helps.
