The problem with that is.... are you going to turn off that switch every single time you park your vehicle?
Before my Excursion was stolen, a wire for some unused component in the engine bay came adrift and got sucked into the power steering pump pulley, it shorted out and blew the ECM fuse, rendering the Exy DRT (dead right there). Was an absolute booger to figure out.
Then my truck was stolen. ***stolen truck! Please read***
I have a viper smart start system that works off my cell phone. Which means there is no practical range limit. I can be in Chicago and start my truck in St. Louis. It has a channel to pop the trunk that I don't use. I have since wired a relay in to that channel that will ground out that unused hot wire in the engine bay and blow the ECM fuse.
If anyone steals the Big Unit again, all I have to do is open the app, press the trunk button and bzzzt, it will die and be un-startable right then, right there. And just in case the crook is semi-intelligent, I have that relay wire up to seal itself on after activation. If he sees the fuse is bad, and replaces it, it will just blow again. You have to physically pull the relay out of its base to reset it.
Don't screw with a man who really knows electricity.
