This should help tell you how.

The armrest comes with an aluminum-cast mounting foot which goes inside the console, and uses existing studs, you supply new nuts (use self-locking ones). To install it, you must remove the center console from the shifter back, and cut a hole in it for the armrest to go through. My car had a die mark (faint) where the hole would be made at the factory if so ordered. After this, the armrest and the foot get bolted together, with the center console with new hole between the two parts. Now re-install center console, and then fasten the foot to the floor with the self-locking nuts. In other words, you fasten the armrest to the console, not to the floor first. This may sound confusing, but once you have the two parts at hand, the logic will be simple.
