Installation Instructions

Common wiring errors:

1. If the horn does not sound and the relay does not click, check the connection between the blue and white wires. Ensure they are connected to the original car's power supply.
2. If the air pump whines but the horn does not sound, reverse the positive and negative connections at the air pump. Yellow wire to positive, black wire to negative.
3. If the horn sound is unstable, ensure the black wire is grounded properly. Remove any paint or debris that may affect the connection.
