Hello guys, my perkins 4108 on a Seamaster 27 cruiser has no ignition switch (I'm doing a restoration). I have a new switch, but need help with the wiring. There are wires for the switch present, but I want to know what goes where. The switch is 4-wat - Off, On, Glow-plugs and Start. The simpler the better, please. Thanks. e-mail is harry.pinnochio.bond58@gmail.com
