Connecting the wiringFirst you need to remove the plastic trim behind the Eyesight cameras (with the sunglass holder and map lights)
Pop the sunglass holder open and remove the two phillips screws inside it.

Then start pulling the trim down from the back edge. It takes a firm pull to get this started. Some plastic trim removal tools could help.

Once that is free, you need to pull it backwards while pulling the front edge down. There are some clips at the front which won't let you pull it directly down (or will break if you do!)
There's two electrical plugs to remove. A grey one for the sunroof button (if you have one), and a white one for the map lights and microphone.

You then need to remove the two sides of the shroud around the mirror mount. This is hard to get started, but they will slide apart, driver side first, then the passenger side.

Then remove the black plug for the mirror power

You need to push where the small red circle is below, to release the plug lock.

(note, there is a huge unused cavity inside the mirror mount. I have seen an older model Outback that had a third camera in there.)
