ok first off. I was clueless looking around the taillight housing for mounting points. I just don't put enough effort in figuring these kind of things anymore, a few years ago I would have been determined to make it work. now there's plenty of things that distract me, or interest me more.
so for $10 more than the cargonet cost itself, I had it installed while I was at the dealer.
hopefully these pics can help anybody that would install it themselves.
not the best pics, but you can see where the anchour points are.
