Notes: The horn should be installed away from the engine for optimal performance. -The relay's working current must be greater than 10A. -The relay's main power supply wire should be 2.5mm² or larger, and the output wire should be at least 1.5mm². The negative (ground) wire must have a solid connection to ensure proper function. -The horn's air supply should be drawn directly from the air reservoir for better sound quality. Regularly drain the air reservoir to prevent moisture buildup that could affect the solenoid valve's performance.
