B6 Retrofitting B7 interior

[jerr]

I have a 2010 R36 and is trying to convert to B7, stuck at wiring especially the EPB...
I believe I have everything hardware needed taken from a B7

I had a look at Kamold's guide but still quite confused.
Looked at this but it is in German and does not go into the details:

Ups, bist Du ein Mensch? / Are you a human?

Does anyone have a detailed guide on how to do the wirings for a B6 > B7 retrofit?
If anyone in Sydney knows how to do it I wouldn't mind paying for the trouble

The erwin wiring diagrams will be your friend; it's pretty much comparing the diagrams between the two car models.

Are you going full conversion? CCM and BCM too?
