I have a new Yanmar ignition switch (type C panel) with 5 terminals that I can hook up like the old one. My problem is with the three additional wires (P1 P2 and AR) that apparently (looking at the wiring diagram) are for a 6 meter extension harness. On the old switch, those 3 wires disappear inside the switch (which doesn't want to come apart) and I don't see how to remove them and reattach them to the new switch. Do I need them? Anybody here know what I'm talking about? I don't.
