Step-by-Step Installation Guide

1. Prep Work

Disconnect the Battery: Always start by removing the negative terminal to avoid shocks.
Locate Mounting Spot: Most users install the converter near the air filter or behind the grille for discreet placement.

2. Wiring Setup

A. Remove Corner Light Connectors

Unplug the parking light and turn signal wires (leave the ground/black wire intact).

B. Route Wires to Converter

Run three wires from each corner light to the converter:
1. Parking light (to converter’s brake input).
2. Left turn signal (to converter’s left turn input).
3. Right turn signal (to converter’s right turn input).

C. Connect Output Wires

Link the converter’s output wires to the bright filament on each corner light (where the turn signal was attached).

3. Secure & Organize

Bundle wires in a loom and tuck them behind the grille or under the airbox for a factory look.
Use zip ties to prevent dangling cables.

4. Test Your Work

Reconnect the battery.
Turn on parking lights—they should glow brightly. Activate turn signals to confirm they blink normally.

Pro Tips for Success

Label Wires: Use colored tape to avoid mix-ups.
Double-Check Connections: A loose wire can cause flickering or failure.
Weatherproof: Seal connections with heat-shrink tubing if exposed to moisture.

Troubleshooting FAQ

Q: My lights won’t turn on. What did I do wrong?

A: Verify all connections are secure and the battery is reconnected. Test the converter with a multimeter.

Q: Can I use LED bulbs with this setup?

A: Yes! LEDs work perfectly and draw less power—just ensure your converter is compatible.

Q: Is this modification street-legal?

A: Laws vary by region. Avoid red/blue tints, and ensure lights don’t blind other drivers.
