I'm in the process of taking off intake manifold of my 545i and I started with wiring harness that is mounted to it. I got all cables disconnected, but I can't figure out one. Its on passenger side right by the heat curtain. It's a 1/2" thick conduit with bunch of wires inside that goes straight down behind the engine. Anyone knows where does it go or where to unplug it ?

Sounds like the transmission harness. The bundle also includes wires for the crank position sensor and the sensor attached to the oil pan.

Also if you are just removing the intake you don't need to remove the trans harness. If everything else is disconnected, use 2 small bungees and tie the 2 junction boxes up vertical to the wiper arms. This will give enough room to work around.

Thanks guys. I'll keep it as is and just pull it up.... Less stuff to hook back up.
