To remove the little white plug, take a small flat head screwdriver, and insert it between the plug and the casing, in the middle, on the upright side (not where the plug rests on the casing). Gently, turn the screwdriver clockwise, an push the terminal side (where the wires are) towards the passenger side of the truck. The plug will swing out and release itself. Plug tells the truck the key is in the ignition.
