its easy, kind of stealthy, and doesn't require you to drill through, usually multiple layers of sheet metal. can't remember if there's rules about switch mounting location... but that
may play a role. the purpose is to have an external switch track crew can use to shut off power to the vehicle incase of a crash.
lots of people have rigged up "exploding packages" for those assholes. i like the ones that use 12gauge shotgun blanks. people freak out thinking they're being shot at. also remember a glitter bomb one that went off when opened. and even a dog shit cannon that shot dog shit when opened

there are videos for days on the subject.
i also like the videos where the thief gets hurt. like the fat chick who slips and breaks her ankle

there was also a good one i remember seeing where the homeowner came out and lit the thief up with a paintball gun
