I did a continuity yesterday with a cut wire plugged into it to see which of the 4 wire connected to which of the 7 pins and the results were
Tp1 - red
Tp18- unused
Tp11 - white
Tp5 -green
Tp3 - unused
Tp13 - red
Tp16 - black
Not sure of the two unused pins are something my standard usba 3.0 cable didn't support but the controller functioned through the connection before I cut the wire.
