There is only one accessory that I can’t quite figure out. It’s the cargo shelf organizer part # 08P11-TRW-100A. About $60. Can anyone tell me where it goes exactly? Anybody got one? And for that matter what/where is the cargo shelf it’s supposed to be organizing? The picture and placement diagram don’t make much sense to me via a vie the shape of the trunk and the trunk tray that sits in the rear lower part of our trunk. Somebody help the old guy here!
