Have you ever tried pressing the start button to get the horn to sound off?

I did.....was installing a horn this morning and had everything completed and decided to give it a test. Kept hitting the button (what I thought/swear was the horn) and nothing. now I am pissed double checked everything and still nothing.... Decided to walk away because I was getting ready to pull it all off. few minutes later I came back and hit the button again....this time the right one and "vois la" it works. I was hitting the start button on the other side of the handlebar instead of the horn.

Rough morning for me.....
