Just checked my car - the 2 pin connector as pictured above is there (for the spoiler) but the 4 pin connector for the camera is not.
Looking at the wiring diagram, the segment of the harness which goes across the trunk lid is separate from the rest of the harness - so there must be 2 versions - one with the connector, and one without. Also - for the trunk lid itself, it is available in 2 versions - 1 with navigation, and one without - I am guessing the with-nav has the blank where the camera goes punched out, while for the non-nav (which is what I have) it is not (so you can see the depression in the lid where you would penetrate for the camera, but the hole has not been made)
