JUST the SIDE CLIP shown in the main image box.. not the black switch - looks a bit like  a crook lobster...sometimes officially known as a contact switch.... often lost or broken on NON TILT columns.

If lookng for the black Contact Switch for the TILT colunm.. use PW221102C

This is on the side of the ignition lock and helps activate the lgnition lock buzzer.... and is a proper PITA to get to.

Different years use different buzzer boxes but this clip is pretty much  for 69-about 81 GM US.
