4. Setup and Installation

Follow these steps for proper installation of your NAOEVO Wiring Harness:

4.1. Wiring Diagram

Refer to the diagram below for a visual guide to connections. This diagram illustrates a 4-lead setup, but the principles apply to the 2-lead version as well.

4.2. Connection Instructions

1. Prepare Wires: Ensure all wire ends are clean and stripped appropriately for the connectors.
2. Connect to LED Light Bar(s):
   • Connect the Black Wire from the harness lead to the Negative (-) terminal of your LED light bar.
   • Connect the Red Wire from the harness lead to the Positive (+) terminal of your LED light bar.
   • Connect the Yellow Wire from the harness lead to the Memory Function Input of your NAOEVO 6-mode LED light bar. This wire is crucial for mode switching and memory function.
3. Connect to Vehicle Power:
   • Connect the main Red Wire from the harness (typically thicker, coming from the relay/fuse) to the vehicle's Positive (+) battery terminal.
   • Connect the main Black Wire from the harness to the vehicle's Negative (-) battery terminal or a suitable chassis ground point.
4. Mount the Control Switch: Find a convenient and accessible location within your vehicle's cabin to mount the ON/OFF and MODE control switch. Ensure the wiring for the switch is routed safely and securely.
5. Secure Wiring: Use zip ties or other fasteners to secure all wiring, preventing it from dangling, rubbing against sharp edges, or interfering with moving parts.

4.3. Fuse Installation

The wiring harness comes with an inline blade fuse pre-installed, acting as the primary protection against overcurrent and short circuits. Two extra fuses are provided for replacement if needed. Ensure the fuse is correctly seated in its holder.

4.4. Harness Lengths

The harness is designed for flexible installation:

• Length from relay to lead: 10 feet (3.05 meters)
• Length from relay to power button: 6.7 feet (2.04 meters)

For 4-lead harness, the total approximate length from end to end is 19.68 feet (6 meters).

• ON/OFF Button: Press this button to turn your connected LED light bars ON or OFF.
• MODE Button: If you have a NAOEVO 6-mode LED light bar connected, press this button to cycle through the available lighting modes.

5.2. Lighting Modes (for compatible LED light bars)

The harness supports the following 6 lighting modes:

1. White
2. Amber
3. White + Amber
4. White Flashing
5. Amber Flashing

6. Maintenance

• Periodically inspect all wiring and connections for signs of wear, fraying, or corrosion.
• Ensure all terminals are tight and secure.
• Keep the control switch clean and free from dirt or moisture.
• If a fuse blows, replace it with a fuse of the same amperage rating.

7. Troubleshooting

• Lights not turning on: Check all power connections to the battery, ensure the fuse is intact, and verify the ON/OFF switch is functioning.
• Modes not changing or incorrect: Ensure the yellow memory wire is correctly connected to your compatible NAOEVO 6-mode LED light bar. Check all connections for looseness or damage.
• Intermittent operation: Inspect all wiring for loose connections, damaged insulation, or signs of corrosion.
• Fuse repeatedly blows: This indicates an overload or a short circuit. Disconnect the light bars and check the wiring for any shorts before replacing the fuse. Do not use a higher amperage fuse.
