the ballast resistor has been my go-to suggestion for years now. the theory of course being that if the truck starts but stalls, they might assume it was just a pos truck. might be enough to get the amateurs. I now add in a second idea of a fake killswitch under the dash, but not too hidden. let the thief find something if they are looking. :thumbsup: it just doesn't do anything.
or better yet, make it trigger an alarm! :yes:
