I have that kit sitting in front of me now. My question is, there is another part referenced in the retrofit guide above, 51 95 0 421 324, that seems to be applicable for the auto-dim mirror without the Homelink buttons. My reasoning for questioning this is because I'm assuming that the wiring harness for the Homelink mirrors has more wires bundled in it and they wouldn't be used with a non-Homelink mirror.
