Testing auto dimming rear mirror BMW 3, 5, 7 series

Soon I will post a video of the entire installation procedure in a E46. How to connect the cable harness to a GND, Ignition and Reverse ect.

Would you happen to know of any common faults for why the autodim mirror doesn't dim? Mine doesn't work so I have opened mine up and directly applied to power to the electrochromatic mirror and it successfully dims. Are the sensors prone to failure?

[@DiscoFang]

You didn't test the sensor on the mirror face.

Great video! I have two bmw e46. Danish one, and German one. I will use the german one as a "donor" for nice features like this auto dimming mirror.

Which ampere/voltage have you used? It’s possible to damage mirror?
