Installing a KILL Switch and Alarm...?

[Lonestar10]

If I was going to do it ied put a nice robust switch on the ignition power to ecm and tuck it in somewhere easy to get but hidden from sight. If you want expensive you could go with the code entering thing tmc uses.

Glass break sensors from ring tied to the alarm would work in that instance. Could maybe do door ajar sensors mounted to doors or some how tie the door ajar light switches to trigger an alarm when armed

Trucks are quite easy to break into doing no harm I remember hearing at one point that most trucks only have a few different key shape variations.
