Can I upgrade a bmw f10 MY 2012 to NBT without using an emulator? I got all the modules from the same donor car. NBT , ATM module FRM JBBE ZGW 2 8SK CAS4 WITH KEY. and the entire wiring harness. How do I get this all bench tested before placing in the car? If so how?  A Wiring schematic  would really help. my very limited understanding is that CIC and nbt run on 2 different busses. Where does the bus originate? For this am asking could I simply find the KCAN 2 and splice that to the origination point of the  kcan1bus? If not can I make my own adapter harness? All without an emulator?

its possible to retrofit nbt without emulator, you need to generate and inject FSCs.
You can flash your ZGW to ZGW2, so you don't have to replace any modules.
