I have an '08 E92 with iDrive and the following features:

S609A Navigation Professional
S620A Voice Control
S640A Preparation f tel.installation univesral

I bought the MULF2 unit that ThumperX used in this installation. I also bought the other related parts, but my question relates to the MOST cables behind the rear seat. I opened the area up and saw the 2 connectors. In the retrofit guide, it shows one connector with 3 wires and one connector with 1 wire.

However in my car, I have the one connector with 3 wires, but the other connector has 2 wires. So my question is, do I still do the swap of those wires, and which wires do I swap? I can provide photos and more details if necessary. Thanks
