Someone did do a post/thread on that a long time ago. Often only the housing is needed but the pins/connector pigtails are available as well, FCP used to show quite a few of them.
I'm pretty sure I have a replacement BMW IAC connector housing from FCP that I never installed somewhere in my boxes of parts because I never got back to that area and the old one is still holding on.
