MOTOR

A `generic' cable from eBay (these vary)

A+ RED
A- GREEN
B- BLUE
B+ BLACK

My generic cable has A- B- twisted at the motor end so not usable with my motor on this board without swapping the centre pair of cables (at either end).

PORT

1  2  3  4
2B 2A 1A 1B
B+ B- A- A+

Schematic

The Schematic has a missing pull-up resistor of 100K on the SLEEP/RESET pins (named SLP) on each motor controller unit.
