mine is missing something. I popped out the horn button and someone had bent the middle horn assembly into itslef rendering it useless, I straightened everthing but I cannot figure out how the center node touched the metal backing of the button itslef. does it have another peice that I am missing? so far here is what I have: top button with metal insert and ring inside brass? ring that is held down with center nut insert that goes inside the column and a wire attached comes out the side of the shaft about 4 inches down. thats it, I am wondering how the center gets to touch the metal on the cap to complete the circuit but I cant figure it out, clearance is too tight for some kinda spring and I dont see how this thing can do it in this setup. I tried looking online and couldnt find a thing.
