assume the posts are labelled.
B (battery) = 12V feed from battery.
S (start) = through neutral safety switch to starter solenoid small input terminal
C (choke, if equipped) = to choke solenoid
A (accessory) or I (ignition) = 12V switched accessory (gauges, other accessory that are powered only when the key is "on").
M (magneto) and other M (magneto) -- if your motor has points, attach the two wires coming off the points here. If it has electrronic ignition, put a ground on one and the kill wire on the other.
