Regarding a 53 Chev 3/4 ton....

Just starting on this truck - the plan is to get it to road worthy daily driver status before doing the full restoration. The original wiring is hanging from the frame - most with no insulation. Even without an electrical engineering degree I'm guessing this is a problem! :o) I'm planning to replace the splash-lube 216 with a 235.
I have two questions:

Can someone direct me to a source of info and parts on the best way to proceed with a complete rewiring of this truck (with 12v and turn signals)?

Can someone direct to a source of info and parts for converting from 6 to 12 v?

I know this info must be out there somewhere but I haven't stumbled across it yet.

Thanks for your guidance -
