Another thought...
As I shared in another thread, I had my J-Spec rear fog light installed in my new roadster last Friday which is a modification that I recommend as the rear fog does, I believe, make your vehicle much more visible in low-visability conditions such as fog or heavy rain.
As with my coupe, to which I also made this mod, I had this work done at a local dealership and by a tech who's been with the same dealer for almost 25 years.
In both installations, he ended up CUTTING the studs that held the dummy unit in place because these things are fastened on at the factory with lockite that just loosening the nuts is extremely difficult.
All this to say, if you are going to make this modification or something similar and plan to do it on your own; just be prepared for this problem...other than that, the installation is pretty simple and straightforward.
Happy motoring!
