Retrofit rear view mirror 9134459

[Hotter]

Hi did anyone retrofit 9134459 auto-dim+alarm led rear view mirror?
Is there a tutorial how to do it? which pins do I need to connect? Its not very clear from Ista, which ones do I need for this mirror specifically?

Do I need 7 wires for this mirror? And no coding for auto-dim?

And for coding part should I add 431 VO code and reset FZD?
