Where could you hide something like that where it would be hard to find? Once found, all a thief would need would be a short jumper to render it useless.
On my '49, it was in a boxed section of my Camaro clip. It wasn't easy to get in but I only had to do it once. Once it was in, there was NO access to the backside of the switch.
How many thieves carry a short jumper with them unless they are premeditating.
If somebody wants your truck bad enough, they will find a way to take it. The idea is to make it as hard as possible for them to do that. Thieves don't like hanging around long. So trying to diagnose a dummy coil wire or no power to starter usually makes them move along to an easier target.
