Lane Assist O3 FL retrofit problems

Hello, dear forum members
I have an Octavia 3 FL from 2019 and recently decided to retrofit my car with Lane Assist. 
I was looking for information how to connect the camera on the Internet and I even found a few deturials on how to do it,
I have already purchased everything, the window has been changed, the camera inside the car is connected according to this guide https://mqb.pl/en/tutorial-retrofiting-lane-assist-sign-assist-light-assist-5q0980653/
 and everything is coded as shown in this video https://www.youtube.com/watch?v=IWqMtPScIkY . Although the guide is based on the Golf MK7, but is the same as Octavia. Or not ?
I only did not connect pins 1 CAN-L and 7 CAN-H from the camera to the ACC radar, but in the first link the author writes that it is not necessary.
But after coding the camera keeps giving me the Can Bus communication error all the time - Databus missing massage U112100 with ODBeleven. Other systems (44, 17, 5F) do not have errors related to adding a camera.
So I thought it might be because the camera is not connected to ACC radar.
So I took apart the front of the car to get to the ACC radar connector, and I was surprised. Because there are already cables connected to pins 6 and 5. 
But not like in my diagram ,pin 5 orange/white and pin 6 orange/brown in the diagram, but pin 5 orange/red and pin 6 orange/brown.
And now the question is what are these cables connected to? The diagram does not show that they need to be connected to an existing harness.
Have any of you already retrofitted a car after a facelift with Lane Assist, or do you have any links to where it was done?
Maybe these two guides were Mk7 Golfs, but from before the facelift? And maybe the connection of cables before and after the facelift is different?
There is a lot of information on the Internet about this retrofit, but 95% of them are golfs from before FL.
If anyone also has directions for the source of electrical diagrams for O3 after  facelift, I would also be very grateful.
