The radio knobs just pull off. The headlight switch has a little button behind the dash on the switch. It's about 1/4" diameter and silver. It's on the side opposite of the wire connector.Pull the light switch knob as far as it'll go, then push the little button and the knob and shaft will pull the rest of the way out. Just push it back in to install.....ya may have to give it a little wiggle.
