Thanks Gold! That's very informative. A few questions.
1) Do you know where that auto headlight sensor is? Maybe on the back of the actual mirror case or on the base somewhere where it connects to the windshield?
You mentioned the two connections plugged into the mirror are for the rain & dimming sensors.
Once the cover is off you will be able to access the connectors for the rain sensor and the dimming/light sensor connector on the rear of the mirror.
With the two electrical connections unplugged...
2) Does the light sensor for the auto headlights have a power plug to it or does get it's power from the auto-dimming power feed? I don't have rain sensors so there should only be one plug?
