How to add Auto Dimming Wing Mirror

[Dofus]

Hello
i have a 2013 1.4 Tfsi A3 SportBack. Yesterday i managed to get auto folding mirrors installed on my car.

to my surprise there is line on the edge, the wing mirrors are also auto dimming. I already have a rear-view mirror that dims automatically. I'm not sure what I need to do to get the auto-dimming wing mirror to work.

Thanks

I will try and dig out the wiring diagrams from whe I did this to mine.
