By disconnecting the connector from the board, you can see a picture as in the photo. The purple mark is the first pin of the connector. Let it be #1, and let it be #2 to the left, then:

#2 will be B11 & #3 will be B10

#5 will be A2 & #6 will be A3

#8 will be A10 & #9 will be A11

#11 will be B3 & #12 will be B2

In the second row, same counting from the right:

#4 will be D+ & #5 will be D-
