Just in case someone want's to pull their's apart it's quite simple...

1. Open center armrest and pull storage bin up and out
2. Remove 2 sheet metal screws (#2 Phillips) from rear of storage bin, near hinge
3. Pull buttom of rear vent from above rear cupholders (open rear cupholders first)

For installation, line up the fabric ductwork with the rear vent while pushing the rear vent in place.
