Update. I'm still at work, but I couldn't help it. I started up the truck, and tried to use the key to shut it off. Nothing, still running. So I unplug the switched 12V wire and the truck shuts off. Kinda wierd. I'm going to see if I can find another switched 12V source, and try that. I'm kinda stumped here. John
