In that thread, Craig Elder’s schematic snippet is correct (and can be confirmed on the fifth page here), and Touotune06’s wiring diagram (with the picture of the Pixhawk) has the wire colours aligned with the correct pins, but the labels they specified for the green and white wires are the wrong way around (i.e. the green wire should be labelled as D+, and the white wire should be labelled as D-)
