wiring a aftermarket horn with relay

[joe 1950]

I want to thank all of you for your help the wiring diagram was very helpful i figured it out and got the relay to work with the horn button the new aftermarket market horn would work but sound was terrible so come to adjust the screw for tone only to find it was stripped out my buddy had this horn about 10 years ago so i think the warranty is off but everything works as it should thanks again
