The numbers in the first row of the table (under No.) is the pin in the connector.
The second row tells what component the other end of the wire connects to, and the number after the colon ( : ) says which pin it connects to in the plug on the component.
The third row describes the colour of the wire. OG-BK = Orange/Black, BK = Black, OG-BU = Orange/Blue.
All of that is from the Wiring Diagram for P1 cars that I've downloaded from a Volvo support website, which I can't recall right now.
If you have removed the panel over the tailgate, you can shine a light in over the D pillar panel, into the corner of the car roof. You should be able to see the connector in there. Accessing it requires removing the D pillar panel, which I haven't done myself, but there should be no need to drop the headliner to access this plug.
Best of luck.
