Nilight 14AWG LED Light Bar Wiring Harness Installation Guide

Quick guide from the manual

This guide covers the installation of the Nilight LED light bar wiring harness. It is designed for 12V DC systems. Ensure your light bar wattage does not exceed the harness capacity (300W for 14AWG, 450W for 12AWG). Always tape off unused wire connections to prevent short circuits.

Installation steps

1. Connect light bar wires to the harness terminals (black to black, red to red).
2. Run the rocker switch wires through the switch cutout in the dashboard.
3. Connect the wiring harness to the car battery: red wire (with fuse) to positive, black wire to negative.
4. Turn on the power and press the switch to test the light.

5-Pin rocker switch connection

The 5-pin rocker switch allows for different indicator light behaviors. Ensure you tape off any unused wire connections to prevent shorts. The pin-tab outs are as follows: 8 (Upper Light Neg), 2 (Incoming power), 3 (Outgoing to relay), 7 (Lower Light Neg), 6 (Lower Light Pos).

Wiring methods

Choose one of the following methods to complete the switch connection:

• Wiring Method A: Connect the red jumper wire from pin 2 to 6. The lower indicator light will turn on when the key is turned on.
• Wiring Method B: Connect the white jumper wire from pin 3 to 6. The lower indicator light will turn on only when the switch is turned on.
