Guys, this is exactly what saved my car. The thieves got past a dual alarm system, and multiple kill switches. They pushed the car about 3 blocks and couldn't get it started, so they popped the hood and proceeded to test every wire in the bundle that came from the alarm system. The bundle was about an inch in diameter. Right next to it was the fuse holder for the fuel pump. It must have looked like a fuse for the alarm system, because they locked the doors and walked away from it.
You can run that wire into the cabin and put multiple kill switches on it also. Kinda like the deal where you put 6 locks on the front door to your house and only lock 3 of them. That way when someone tries picking the locks, they are always locking 3 of them.
