What's the cleanest way to wire a cut off switch

My time was irreverent alright as well as nhra national record holder in the mid sixties for AA/MSP " Instant Motion " Dodge powered Cheetah.

Sorry I am no help to the poster's question yet at least I haven't any negative statements as well... I always wondered what it felt like to be perfect, can both the kid and 67Dart273 explain what it's like?
