Wiring a Stebel Horn

[jarhead]

I need a little help figuring out how to wire the Stebel using the aux fuse panel for power and the original horn button. Which wires run to the aux fuse panel and horn button and which ones go to the Stebel? The diagram on Gadget shows installation using a relay switch going straight to the battery. With the Aux fuse panel I should not need the relay, but I can not get a picture in my little pea brain of where the wires should run if you take the relay switch out of the picture. Any help will be most appreciated.
