2009 Opel Insignia A20NHT 2.0 Turbo Wiring Diagram: Cable Connections, Xenon, Sensors, and Colors

Hello, I have an Opel Insignia 2009 A20NHT 2.0 Turbo petrol.
Xenon, sensors on rocker arms etc.
A burnt beam goes through the bulkhead wall. Torn cables.
After connecting the cables according to the colors, it turns out that from the right side there are 19 cables to the wheel arch recess, from the left side / driver / There are 20 cables.
1.
The problem is I have two brown and yellow cables. And one of them, the thicker one, remains free for me. I don't know what to attach it to.
2.
The second thing is that there are two thin yellow cables and two brown and black cables.
Anyone have a wiring diagram.

One brown-black and yellow cable goes to the accelerometer and the other two go to the plug on the rockers

An additional question is whether the yellow cables on the 1817 circuit can be swapped with the yellow one which, according to the photo below, is on the same circuit. A similar situation with the black and brown cable.

I read it carefully but I don't understand.
The yellow one on the circumference of 1817 is in my opinion given once for the left-hand drive LHD version and the second time for the right-hand drive RHD version. There aren't two yellows there.

In the bundle that runs along the bulkhead wall, 2 yellow, 2 black and brown are led. From the driver's side, 2 black and yellow enters on the windshield, while one exits. And here's the question what to do with it.
