I wanted these but took my delivery from a car off the lot that did not have them. It seems they are only factory installed and not something you can currently add on later. I'd love it if somone could take some pics of the location and what they look like up close. My guess is a year or so from now the parts may be avaliable and I could retrofit them. I need to look at the wiring diagram to see how they are wired in. I have the service manual but have not gotten around to doing that yet.
