According to the current flow
PDF here, this is what I found:
1. The anti-dazzle wiring is linked to Y20 in the following image. This is from page 118:
2. The heating wiring is linked to Z4 in the following image. This is from page 117:
Looking at the image you provided, I believe the heated feature are the two spade connectors on the right side of the photo, as the same feature on the D2 mirror on my car is located there, and mine definitely didn't have anti-dazzle. They are certainly dark coloured wires, but you'd need to clean them to see if they are indeed black and black/blue. As for the other connector, it looks like the wires are black/grey and black/green, although I always thought that the secondary colour was the minor colour i.e. the thin stripe.
As for the old glass, there might be someone out there who could make use of it, for the cost of postage, especially when some of these mirrors cost up to £500, depending on the functionality.
