5.1 Controller Wiring (Pin Definition)

Carefully connect the controller to your motor and other components according to the pin definitions provided. Ensure all connections are secure to prevent damage.

Key Connections:

• Hall (waterproof): Connects to the motor's Hall sensors. Wires are black (Hall GND), red (Hall 5V), yellow (Hall signal), green (Hall signal), blue (Hall signal), white (Temp sensor).
• Ignition: Brown wire for Ignition B+.
• Throttle: Red (throttle 5V), black (throttle GND), green (throttle signal).
• Three Speed: Blue (low speed), green (high speed), black (GND). Plug-in for high speed.
• ONE-LIN Speed & Cruise: Brown (ONE-LIN speed sensor), black (ONE-LIN cruise).
• Reverse: Brown (reverse), black (GND).
• Low Brake: Yellow/Green (low brake), black (GND).
• High Brake: Grey (high brake 12V).
• Alarm Power: Pink (alarm passive), red (alarm power).
• Anti-Theft Motor Lock: Brown/Red (motor phase signal), black (GND).
• Program Port: Red (power supply), black (GND), blue (RXD), green (TXD). Connects with Bluetooth adapter.
• Bluetooth Adapter: Connects to the Program Port for PC & Phone programmability.

Important: The controllers are universal versions. Some auxiliary functions of the original vehicle (e.g., speedometer display) may not work normally after installation. Most functional interfaces may require modification rather than being plug-and-play. Always verify the function lines on your original vehicle and the speedometer communication signal before making modifications.

• Avoid exposing the components to extreme temperatures or direct water spray.
• If any issues arise, consult the troubleshooting section or contact support before attempting repairs.

8. Troubleshooting

This section addresses common issues and questions related to the FarDriver controller and DKD display.

8.1 Common Issues

Q: Some auxiliary functions of my original vehicle (e.g., speedometer display) are not working after installation.

A: The FarDriver controllers are universal versions and are not custom-made for specific vehicle brands. Therefore, some original auxiliary functions may not operate as expected. Most functional interfaces may require modification rather than being plug-and-play. Always carefully check the function line on your original vehicle and the communication signal of the speedometer before attempting modifications.

Q: The DKD display voltage reading is incorrect after changing the battery.

A: If you change the lithium battery type, you must power cycle the display for the new voltage settings to be recognized. You can also use Password 856 to select the correct voltage (48V, 60V, 72V, 96V) or Password 824 for self-input voltage calibration.

9. User Tips

• Professional Installation Recommended: Due to the technical nature of the controller and display, it is highly recommended that installation and wiring be performed by individuals with knowledge of electric kits assembly to avoid man-made damage.
