As the title says, I need to wire my build from scratch. It's a '50 3100. I have no wiring harness or really any good idea of where to begin but wanted to ask for some direction before I needed to know in the next couple of weeks.

The engine is a '60 235, 12v starter. I'd like it all to be 12v and I'm hoping to use an alternator if I can source a bracket for it.
