- Connect the wires for the left switch (turn signals, horn, high/low beam) to the corresponding circuits on your motorcycle.
- Connect the wires for the right switch (headlight, ignition, stop) to the corresponding circuits on your motorcycle.
- Ensure all connections are secure and properly insulated to prevent short circuits.

- Cleaning: Periodically wipe the switches with a damp cloth to remove dirt and grime. Avoid using harsh chemicals or abrasive cleaners.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Switch not functioning | Loose or incorrect wiring connection. Blown fuse. Faulty switch. | Check all wiring connections for security and correct polarity. Inspect motorcycle's fuse box for blown fuses and replace if necessary. If wiring and fuses are good, the switch may be faulty and require replacement. |
| Intermittent function | Corroded connections. Loose internal components. | Clean electrical connections with contact cleaner. Ensure the switch is securely mounted. If the issue persists, consider replacing the switch. |
| Buttons feel stiff or sticky | Dirt or debris accumulation. | Clean the switch housing and buttons with a damp cloth. Avoid forcing buttons. |
