G20 Sound Wiring Diagram

Hello there!
I need to know what is the remote (REM) wire in the Harman/Kardon bass amplifier harness.

By the gauges of the wires we could guess this:
Brown: Ground
Red: Positive
Purple/Yellow & Green/Black: Subwoofer 1
White/Black & Blue/Gray: Subwoofer 2

And the rest of them:
Yellow: ?
Red/Black: ?
Green + White: ?

Is there any pdf or file with the sound diagram? I didn't found anything online

Thanks in advance...

That looks like an ASD module, not an HK OEM amp.

Seems that BMW is using the chassis of the ASD module for the Booster now: ASD -> Booster

Use fusebox or trunk ACC socket (if available) as the remote wire.

Theres no ACC socket in the trunk

I will try the fuse box. Any hint on what fuses is safe? Don't wanna mess with something or drain the battery out.
Thanks for helping me.
