Charging system

Yes, that was my plan. The electric fan, fuel pump, headlights, starter, and horn are all getting relays installed as well as fuses. I understand that the factory did things a certain way but to me if I can make things work safer, more efficiently, slightly modular and most important just plain nicer, I'd feel much better with it. I do want to add multiple things that will add a fair bit of draw so seeing a harness described as "adequate for the day and underpowered now“ doesn't make me want to reuse it even if it is new. I checked after work and it looks like my parking lights stay on with the headlights. So that's easy enough to copy. My main reason for wanting to do a brand new custom harness is partly for the satisfaction of doing so and partly to integrate all of things I want to add into one system rather than patching a bunch of things on top of each other like the Germans did with their 80s BMWs lol. I realize there are certain things that I'll have to compromise on in regards to connectors and pigtails, but I can live with that. Those will be on an as needed basis.

So regarding the starter circuit, I guess I'll just leave it then. Tail lights look pretty straight forward so I'll do those next. I'm assuming just a single fuse should be fine for 4 1157s and one b56. Same with interior lights.
