A common misconception. The rule for wire colors is
<R81> All wires distributing power with a constant polarity (i.e., except for Relay Module, Speed Controller, or
sensor outputs) must be color-coded as follows:
• Use Red, White, or Brown wire for +12 Vdc and +5 Vdc connections.
• Use Black or Blue wire for Common (-) connections.
Since the wires to motors are not constant polarity, you may reverse these leads to allow the motor to run in the needed direction. You may also make the change in software if you are so inclined. You will not fail inspection for reversing the motor leads at the
output side of the controller.
