Installation of Android Auto/Apple Carplay with COMAND NTG4.0

[SeeDaRipper]

These devices take their power from the multiplug that feeds power to the head unit. A socket accepts the original multiplug, and a new multiplug on the other end of a short breakout harness then plugs into the head unit. So there's no need to tap into a separate fuse.

Thanks, so any idea as to where i put the ACC and BAT terminals then? (My car is in my bio) TIA
