I am retrofitting an OEM rear view camera in my 2017 F31 (VIN K868269).
I am using OEM parts (module, camera, etc.) and following the original BMW instructions (see in attached).

I have installed everything and am currently finalizing the wiring. And that is when I see something unexpected. The instructions call for tapping the Kcan wires from FEM A173 which are pins 51 and 52 using connector H.

However, when I open A173 in my car pins 51 and 52 don't have any wires!

Any ideas on how to proceed? Suggestions welcomed!

Thank you all!

I know it is not the same car (not a F30/31) but this video from KIES shows most of the installation process and is exactly as the BMW instructions.

In the video, the connector A173 DOES HAVE pins 51 and 52 with wires: Jump to min 25:00. So I don't know how to proceed with my installation... any idea on how to connect these wires? Many thanks to all of you.

I don't know if I have K-CAN wires at pins 33 and 34 on A173*7B, but ISTA says that there are K-Can there...

...the same ISTA that says that there are K Can wires in A173*8B pins 51 and 52...

Will need to disassemble the footwell again to check... give me 15min

So I guess that my FEM has no K-CAN where I can tap my wires.
The rear-view camera module is placed in the driver's footwell (left). Is there another option to tap the K-CAN nearby?

I found this in ISTA (with my VIN and also connected to the car), but at this point, I am not too confident in ISTA information because it does not seem to represent my car.

@Markst
Possibility: where is K-CAN created/managed? Is it in FEM? If K-CAN is created in FEM then instead of tapping the wires to existing wires in pins 51/52, I can just connect with new pins there. Would this work?!

@Markst Are these possibilities?
1 -> If K-CAN is created in FEM then instead of tapping the wires to existing wires in pins 51/52, I can just connect with new pins there. Would this work?!
2 -> I am routing these wires from the rear view camera module in the driver footwell to the FEM in the passenger foorwell, passing just next to the HU. Are there KCAN connections in the HU that I can tap?
