Can I disable starting the van but still have accessories (radio) available?

lots of ways to do what you ask- my way would be to just take the coil wire off and hide it in the house- I learned that from "The Sound of Music"

you could run a cable from the battery to a toggle switch and then hook up the radio to that. but then when you were driving you would have to flip the toggle switch to listen to it. but that's really not that big of a deal.

I should have been more specific. Is there a fuse I can remove to disable the starter from cranking so there is no wear and tear on the engine? Thank you for your help
