I am trying to figure out a way to have the engine work off a toggle switch... since my car got stolen I want to place a secret switch somewhere in my car so the next time some one tries to start it,it wont start.
Use a trick starter switch instead of the key.
Wire it so that when you turn the key to 'start'
nothing happens. A thief will give up at that point. No one will know what switch starts the car. You could install your own push-button starter switch run to a relay.
