Adding my 3 cents into this thread, I must inform you that you will have to drill holes in your rear hatch. I purchased my spoiler iin the aftermarket from autoanything.com. In order to get to two of the hole to install the phillips screws from underneath; you have to drill a hole larger than the head of the screw. Also, be careful not to drop the screw down in between the metal body panels or else you will have to take the hatch apart to retrieve it. Of course, you could leave it there, use another screw and always have that persistant rattle if the screw lands in a awkward place. BTW, it took me about 2 hours to intall the thing. I just spliced into the Runner's orginal brake lamp wiring and it worked find. P.S. Do NOT remove the factory 3rd brake lamp when you install the aftermarket spoiler. It will leave a hole in your liftgate. The factory 3rd light is well HIDDEN when you install the aftermarket spoiler. I added the spoiler mainly for cosmetic looks. I can't really say if it adds to the efficiency of the Runner while driving.
