- Connect Motor Wires: Connect the motor phase wires (usually three thick wires) from your front and rear motors to the corresponding ports on each controller. Match colors carefully.
- Connect Hall Sensor Wires: Connect the Hall sensor wires (usually five thinner wires) from your motors to the controllers. These provide feedback on motor position.

- Secure All Connections: Double-check all connections for tightness and proper insulation. Use zip ties or cable management solutions to keep wires tidy and secure.
- Initial Power-Up: Reconnect the battery and power on the system. Observe the display for any error codes and test basic functions at a low speed in a safe environment.
