good basics in this book from Speedway Motors & others - do not let title scare you away - "How to Wire Your Streetrod from Start to Finish" by Jack Sweeden
I wire lots, don't like circuit breakers, in the event of a short, a fuse blows, you have to find it. A circuit breaker will stop, try again, stop, try again, they aren't dangerous, but in a simple wiring job, they can be a real pain. Yes, the book from Jack Sweeden is a seriously good reference to own, simple yet comprehensive, get it.
I like to run an 8 gauge wire for the fuse block feed. Probably overkill, but almost all wire in my Buick is "next size" up from recommended. Ben
