I put a kill switch in mine and it's more a "peace" of mind. If anyone really wanted your truck, all they'd have to do is pull a gun while you're at a stop sign and it's their truck frown .

Years ago, my father in law made, out of thin gage wire an alarm connected to his horn. He positioned the wire as such that if the truck tilted like when somebody got in the truck, the wire would ground itself and the horn would sound. He foiled a couple of attemps of stealing his truck. Then he finally sold the old '40 Chevie truck and bought a newer Fo*d and never had a problem again. Go figure :confused: .
