I connected mine together at the motor leads and then ran four #18 wires to my Xylotex control board for the following reason:
If you extend the eight wires to the control board before tying them together in bipolar parallel you would greatly increase the effective inductance of each coil that is wired in parallel. The long wires on each end of a given motor coil become additional inductors in series with each motor coil.
In my case, the motor wires are around six feet long.
