- Auxiliary Components: Connect headlights, turn lights, brake lights, and horn to their designated connectors.
- Ignition: Install the ignition switch and connect it to the harness.
- Secure Connections: Ensure all connections are firm and properly insulated to prevent short circuits or disconnections during operation.
Important: Always consult the specific wiring diagram provided by the seller for your exact configuration to ensure correct and safe installation.
3. Operating Instructions
The wiring harness itself does not have operational controls but enables the functionality of connected components. Once installed correctly, the system operates as follows:
- Ignition: Turn the key in the ignition switch to power on/off the electric vehicle's main electrical system.
- Throttle: The Z6 throttle will control the motor speed and acceleration when connected to the controller via the harness.
- Display: The DKD or CT-22 display will show essential vehicle information such as speed, battery level, and other parameters, receiving data through the harness.
- Lights and Horn: Headlights, turn signals, and horn will function as intended when activated via their respective switches, powered and controlled through the harness.
4. Maintenance
To ensure the longevity and reliable performance of your wiring harness, follow these maintenance guidelines:
- Regular Inspection: Periodically check all visible parts of the wiring harness for any signs of wear, fraying, cuts, or damage.
- Connection Integrity: Ensure all connectors are securely seated and free from corrosion. Loose connections can lead to intermittent operation or electrical issues.
- Cleanliness: Keep the harness clean and free from dirt, dust, and moisture. Use a dry cloth to wipe down the harness. Avoid using harsh chemicals or excessive water.
- Protection: Ensure the harness is routed away from moving parts, sharp edges, and excessive heat sources to prevent physical damage.
- Environmental Exposure: While designed for vehicle use, prolonged exposure to extreme weather conditions (heavy rain, direct sunlight, extreme temperatures) can degrade the wiring over time. Consider additional protective measures if your vehicle is frequently exposed to such conditions.
5. Troubleshooting
If you encounter issues with your electric vehicle's electrical system after installing the wiring harness, consider the following troubleshooting steps:
- No Power to Components:
- Check the main battery connection to the harness.
- Verify the ignition switch is in the 'ON' position.
- Inspect the 72V to 12V DC converter for proper operation and connections.
- Ensure the relay and flasher units are correctly installed and functioning.
- Display Not Working:
- Check the connection between the display and the harness.
- Confirm the display is compatible with your controller and harness version.
- Throttle Not Responding:
- Verify the Z6 throttle is correctly connected to the harness and controller.
- Ensure the throttle is not physically damaged.
- Lights/Horn Malfunction:
- Check the individual connections for the affected light or horn.
- Ensure the switches for these components are working.
- Intermittent Issues:
- Thoroughly inspect all connectors for looseness or corrosion.
- Check for any pinched or damaged wires within the harness.
If problems persist after basic troubleshooting, it is recommended to consult a qualified technician or contact SiAECOSYS customer support with your specific wiring diagram.
