STEBEL HORN INSTALL.... I learned of 4 places that the horn would fit on the B650. I'm sorry I lost the name of the person that made the suggestion I decided to use, but if he reads this, thanks a lot. I think it's the best place of all.
The horn is installed behind and below the right hand storage box. The picture shows this pretty well. I used that white plastic packing material as a cushion around the part of the horn that touches the plastic.
