build a starter kill relay and hide the switch under the dash or in the glove box or some place like that. A relay will cost about $5 and a switch $1 or so. You can buy a relay harness with the wires attached if you dont keep the connectors around. Its the same thing that a security system uses without the alarm. Cut the starter wire under the dash. Connect the key side to pin 30, the starter side to pin 87. Tap into a "true" ignition lead (thats an ignition wire that has 12v on even while the starter is engaged)or a constant 12v source and connect to pin 85. Run a wire from pin 86 through your switch and to ground. When ever your switch is open, the relay wont trigger and will not send voltage to the starter. If you understand how a relay works, you can also wire it up to use existing switches in the truck (ex: having to press the brake or turn on the fog lights or press the metric button on the overhead or an unused upfitter switch, etc)
