I borrowed and edited one of the wiring diagrams posted by spencerforhire. I cut out the clutter to make it easier to see. The cars power goes from the battery to the starter motor. There it goes #10 gauge red to a splice which is wrapped in the wiring harness right around the passengerside of the carb. It has constant power to the alternator. The other direction two # 10 reds go toward the bulkhead connector. As they come out of the wrapped wiring harness, one goes to the a/c along the firewall. The other wire is spliced to a fusible link at the bulkhead connector. This is the wire that powers everything else. If you intecept this wire (before the fusible link) and put a on/off switch in it, shutting it off will kill lights, ignition, accessories, fuelpump,choke, you name it. One switch is all it takes.
(by the way, I think it was a cheesy idea to put a fusible link right into the bulkhead connector as if it ever burned up you'd have to disassemble the connector to replace it.)
