Push button ignition switch help to wire

I figured the fuse block had little if anything to do with the ignition beyond dash lights. I have a couple different parts cars from 1971 to '73. As for driving it on the street, it would be like the occasional car show, swap meet. I'd like to be able to keep, repair and use the factory set up whether it be from a donor car or aftermarket. The budget I would prefer to keep cheap, but will spend the money to make it correct.
