gearhead204 1,825 Posted January 16, 2017 is this in an older R model ?.....if so i'm thinking your cab power relay is faulty and power is being back fed some how when the truck is running to make the alarm work. to check remove the ash tray and check the large terminals on the solenoid to see if both have power with the key on.
