On the outside of the ignition switch at the dash, you will see a chrome bezel. Turn the bezel counter-clockwise until it comes off. Once it's off, reach up under the dash and you should be able to pull the switch down far enough to unplug it. There is a special tool to remove those bezels but if your real careful you can use a pliers but you must be very careful or you will scratch and/or bend the chrome bezel.
