Looks like I'm having the same issue. No voltage on that green/white wire, whether ignition is on or off. I have a 2012 135i. Does anyone know what that connector is for? Is there a fuse for it that I might have blown while tapping this power wire?

EDIT: Turns out the wire tap provided by the hardwire kit did not work for the job. It's designed for a larger gauge wire, and therefore was not even breaking through the wire insulation. I used a different wire tap and got voltage. But be aware that the connectors all need to be PLUGGED in before battery voltage is supplied at the green/white wire. Works now!

Thanks for the write-up guys. Especially the removal of that map light assembly. It's a bitch!
