Upgrading to Auto-Dimming Rearview on 991.2
#16
Hello,
I was wondering how did you get the auto dimming rear view working.
I am stuck. I thought I could do away without the LIN cable connected but it is not the case.
I have hardwired the mirror from the fuse box.
It is powered,the green light below is on but the mirror does not auto-dim.
Would really appreciate your help?
Take care.

Thank you for your reply.
Has anyone been able to bypass the Local Interconnect Network?
I have the seen the rain/ headlight sensor has 3 pins as well. Guess the middle wire is for the LIN. Could I tap this one?
Cheers

sure, you should be able to tap into LIN bus but if your system is not sending the LIN commands to address the mirror nothing will happen.

Hello, I am a bit confused. It would be great if you could share the wiring schematic for the 718
From the mirror I have BRN, RED, BLU
From the rain/light sensor I have BLK/RED, BLK, VIO
Thank you for your help.

I am traveling and not near my car. However, the middle wire in LIN. It matches the wiring diagram I previously posted. You had previously already wired 12V and ground?

I tried doing this and it didn't work. For one, the wiring harness (991-612-691-00) is for the rain sensor, so don't waste your money on it. What you need is the yellow plug, which unfortunately is part of the main wiring harness. So what I did was tap 12v and ground, which powered the mirror, but tapping into the LIN cable didn't do anything. I suspect that you need to have the computer programmed for it to function. Anyone else have any luck?
