I've read somewhere that some mustang owners wired their fuel pump to a switch that is hidden inside the car. So in the case of a car jacking, the theif tries to hot wire the car but won't start cause the fuel pump has to power to it. Is there anywhere on the web that shows how to properly set this up?

I haven't found a place but it should as simple as finding the cars wiring diagram and using it to find the fuel pump ground wire so that you can cut it solder in a new wire running into the car with switch and then route back and solder up the other end so that you now have switch to break the ground and don't forget to use heat shrink tubing to insulate the solder joints btw do not try put the switch in the power wire or you will start a fire
