I just bought a factory accessory kit but not sure exactly where in the trunk it goes. From what I have read in the other posts it appears it velcros to the side wall of the trunk. I see the accessory bag has velcro strips on the back of it so does it just velcro to the trunk'* fuzzy surface or is there suppose to be velcro strips on the trunk wall also that matches up with the bag? Thanks

looking into the trunk, it goes on the left side indent right infront of the taillight

Dont think it matters which side. Mine was actually on the right side. Maybe its a personal preference of the Dealer detailer. The Velcro on the kit sticks right to the fuzzy carpet.
