Bcm plug issue tailgate conversion

[Vogels_Garage]

I'm doing a tailgate conversion on a 2021 T6.1

And I was following the guide about tailgate conversion in here , but have a problem. They mention I need to ad 2 wires at a black plug on the bcm. But I have 2 black and a brown plug at my bcm. Which of the black plugs are the one I should use ? Can anyone help me ? They are marked with A B C

Thanks in advance

I think those instructions may be for a T6 which is different
T6 BCM has two 73 pin plugs, 1 white plug and 1 black plug
