im thinking about puting a kill switch under my dash and im wondering how to do it

 

find a wire you want to cut that controls something that wont make the truck start and run it through the switch thats basically the just of it, figuring out what to cut might be a issue. i always use something that controls the spark. that way the thief will either think its a beater and leave it, also you;ll hear the engine cranking. and 3 if he eventually finds the switch id hope the engine would be so flooded it wouldnt start anyways
