Welcome to Just Answer Chrysler my name is Mark.
If you have a tilt steering column you need to remove the tilt lever. the lever is held in place with a single screw. Next you need to remove the plastic covers around the top of the column. There are a couple of screws on the bottom side and then the 2 halves will unsnap so you can remove them.
Now all you need to do is remove the screws holding the switch in place and then install your new switch.
