Trying to retrofit original auto-dimming rearview mirror. Wiring?
 

Hello,

I would like to retrofit original auto-dimming rearview mirror to my 2011 Cayenne, that I found to be 7PP 857 511 H. I miss this functionality a lot.
Someone could share the wiring schema for this installation? I would like to do it OEM, but unfortunately, I don't have a Service & Repair Workshop software for Porsche.
Thanks a lot
