I installed a PowerLock on mine. It seems to work well. It's not so much an alarm as it is a starter interlock. What I like is it automatically arms 45 seconds after ignition shutdown. Works well with my turbo cooldown. I don't believe anyone is taking the truck without a tow truck. I do believe I have found its one weakness. If you really want to know send me an email and I will let you know what it is.
