Yes they are, and in MY2010 the Quadralock connector in the back of the iDrive also changed so you cannot use the regular Metra 70-9003 harness anymore to create a PnP connection without cutting/tapping OEM wires.
I'm working in a solution for this new Quadralock so no wires will have to be cut in the OEM harness.
