W212 H/K Logic 7 Retrofit Questions


I have couple of questions about H/K Logic 7 on a 2011 W212. My car came without the option and I'd like to retrofit it. The cost of the parts doesn't seem to be prohibitive and the labor is doable, but there are two things I'm unsure about:

a) What wiring harness is used to connect the amplifier with the in-door harnesses? I tried to find one in the EPC but I didn't see any wiring harness specific for 810 (Sound System - H/K Logic 7) that would go from the amplifier to the doors. Is it possible that it is part of main floor wiring harness? (There seem to be only one version of the main wiring harness - regardless of car options)

b) What wiring harness is used to connect the speakers in rear door? For front door I was able to find A2125409910 and A2125400532, but there doesn't seem to be such thing for rear door specific for Logic 7.

Any response would be appreciated. Thanks!
