Cannot remember where this plug goes... headliner

So, like every E9x the headliner fabric started to droop. It took sometime for me to get it back in, and for the love of god I cannot remember where this plug, plugs into. Or if it was even plugged in.

2008 E91 Panoramic Sunroof


Any help?!

If that is in the front, at the FZD Roof Function Control Center, it is probably the X1582 8-socket connector, with 6 wires, sockets 4 & 6 empty. If you had one (I presume it relates to anti-theft), the A121b Interior Movement Detector would be attached to that Connector. The 6 wires from that connector should go to the FZD.

If you still have questions, please identify the COLOR(s) of each of the 6 wires, & the LOCATION of the Connector. If the wire has TWO colors, the PRIMARY color of each wire is listed 1st, with TRACER 2nd. Red with Black tracer stripe would be Red/Black (socket #1). Black with Red tracer stripe would be Black/Red (socket #7).

and if the car doesn't have the alarm option , then this plug remains unplugged.
