Taken from another thread about the A2000 floppy cable:
Picture 1 shows the complete cable. Floppydrive number 1 (df0:) is attached to the end marked with a "1" and number 2 (df1:) to the middle connector.
Picture 2 shows the number 1 connector. As you can see the wires number 4 and 6 are crossed, by reversing the wires 4, 5 and 6. The red wire is number 1.
