Help me HeR3tic
HeR3tic,
I heard you are the expert on wiring the Stebel air horns. I got my installed today, mounted to the air box under the left side cover. I discovered the the stock Rocket horn uses a ground horn button, where the hot wire to the horn is always hot and the button completes the ground circuit. This threw the screws to me when I tried to figure out the relay. I found the attached photo on a web site. It this the way you wired yours, and does this work with a negative horn button?
