Fuse #17 applies battery voltage at all times to horn #1 and horn #2. Fuse #8 supplies continuous battery voltage to the horn relay K63. A ground path is provided when the horn switch is closed. This energizes the horn relay K63 and closes the contacts. A ground path is provided for both horns through the closed relay contacts. The horns will continue to sound until the horn switch is opened. The horns are also a part of the theft deterrent system.
