In preparations for a trip down to south America I am thinking about installing an ignition disabler type switch as a extra safety against the truck getting stolen. My idea is to install a hidden switch somewhere such as inside the center console or under the seat so that event if some one breaks into the truck and 12 volt system is disabled so the truck cant be moved. A simple idea would be something similar to a race car kill switch, but im interested to know if any one else has installed something similar or if there is a product made for such applications? In short im fishing for ideas to see whats out there .
