I'm getting close to reassembling my rebuilt M41, so I want to get the switch and wiring into the car. I've installed the turn signal-style switch from the donor car (had to ground it with a wire, as the bracket didn't exactly fit the ignition cylinder). I have one wire going to the fuse box with an 8 amp fuse, and the other wire has been left long, and will go to the switch on the top of the M41. I have no plans for relays, as the OEM switch is on/off.
My question is what would a suitable 12v source be. I assume I want switched 12v, not constant? Can I just splice into one of the switched 12v wires going into the bottom of the fuse box? Or do I need to run a new, dedicated wire from the battery?
