I understand the installation of a kill switch. has anyone thought about designing some sort of push button type kill switch that kills say the full pump or ignition and have in in the face of your detachable radio when the face plate is not in the car power is interuppted to the pump or ignit. and when you put the face in the button is pressed in and the pum/ or ignit. has power. I am trying to make another kill switch for added security since I am moving to an apartment soon.
