Step-by-Step Wiring Instructions
1. Disconnect the Battery
For safety reasons, always disconnect the battery before working on any electrical components.
2. Remove the Old Taillight
Locate the screws holding the old taillight in place and remove them. Carefully pull the taillight out of its housing.
3. Identify the Wires
The taillight should have three wires: a red wire for power, a black wire for ground, and a yellow wire for the brake light.
4. Cut and Strip the Wires
Cut the old wires about 6 inches from the taillight. Strip about 1/2 inch of insulation from the ends of each wire.
5. Connect the New Taillight Wires
Connect the red wire from the new taillight to the red wire from the bike’s wiring harness. Connect the black wire from the new taillight to the black wire from the bike’s wiring harness.
6. Connect the Brake Light Wire
Connect the yellow wire from the new taillight to the yellow wire from the bike’s wiring harness. This wire will activate the brake light when you apply pressure to the brake pedal.
7. Secure the Connections
Use electrical tape to secure the connections. You can also use heat shrink tubing for added protection.
8. Test the Taillight
Reconnect the battery and turn on the ignition. The taillight should now be working properly. Test the brake light by applying pressure to the brake pedal.
Troubleshooting Tips
If you’re having trouble getting your taillight to work, here are a few troubleshooting tips:
- Check the connections to make sure they’re secure.
- Use a multimeter to test the wires for continuity.
- Replace the taillight bulb if it’s burned out.
