    Auto dimming mirror connector

    Hi all. I'm considering upgrading my manual dimming mirror to an auto-dimming mirror.
    I read that most E32 and E34 cars came pre-wired for this feature.

    I removed the left sun visor and the courtesy light and there is no extra connector in that area... however, I do see a white 6 pin connector, near the sun roof controls. Is that the one?

    It doesn't match the description of a 3 pin connector (and the 10 pin connector on the later cars) that I read about online, so I'm confused...
    Any ideas? Thanks.

    My 91 M5 has the same 6 pin white connector. Any luck on if that is the rear view mirror plug? I've been wanting to add an autodim mirror as well.

    I had to reach further over to the drivers side to pull the connector over but mine was a 3pin I think. It was just clipped into the roof.

    The auto-dim mirror I got had the connector clipped off it so I took apart the connector on the car side and just spliced them together

    The wiring convention was simple and I found it through a search on here, I left out the reverse hook up I believe and just did power and ground.
