I saw this online not in person so I dont know about the rear wiper switch.
Here is an example.

I haven't personally done this (a friend has), and there are hardtop wiring retro-fit kits, and different versions of these kits based on if you already have heated mirrors or not. Possibly, that's the difference; as said, if you have heated mirrors you don't need the button, just the new wiring to the rear.
Ah, I thought you saw this in person. I would not always trust the pictures are of the same vehicle. I have found lots of examples of dealers who re-use pic's because they assume nothing is different.
