Now I am really confused.

A google search including the Canare web site tells me that with quad
cable you definitely pair the colours together (like with like), one
colour to pin 2, the other colour to pin 3, and the shield to pin 1.  =

e.g. if I am using cable that has blue and white wires, then I
combine the two blue wires together and solder to pin 3, and the two
white wires go to pin 2.

Are you saying only one blue wire would go to pin 3, and the other
blue wire to the ground?  And one white to pin 2, the other to ground?
