Again, the order of the wires is important. Look at Figure 18-2; we've written the letters associated
with the wires on the back of one of the motors. Starting from the left (while looking at the back of the
motor), the first wire will be soldered to A, the second wire from left will be soldered to B, the third wire
from left will be soldered to C, and the final wire will be soldered to D.
Figure 18-2. Motor wires and their assigned pins on the motor drivers
If you look carefully at Figure 8-2, you'll see that this motor actually has six metal pins but only four
of them have wires attached. If you number all of the pins, left to right, we are only using wires for pins 1,
3, 4, and 6. Pins 2 and 5 are not used.
