Trying to power up this seat. The big input connector is black (instead of yellow) and visible in one of the later photos in the ebay auction.

With what is apparently this control module.

I'm looking for a part number or anything else searchable on BMW's website, or at least some more definite information exactly which car the seat is compatible with, in hopes of identifying some wiring diagram traceable to the power and CAN bus pins.
Unfortunately, '61.35 9' ... 'SM MF/M-HKLA', and other such numbers, do not seem searchable on BMW's website.
So, uh, how should I go about trying to identify the relevant pinout?
