When I got my parts truck it was missing the horn button and the truck I'm putting on the road had a tiny aftermarket steering wheel in it so I have changed them out. I bought a new horn button but can't figure out how the components that make the horn work go together. I have a slightly concave round disc with slots and screw holes in it (5 on diagram), a big round metal part that I assume the button attaches to (3 on diagram), and a plastic piece that looks like the screws go through (4 on diagram) and the main horn wire with a female slide end on it (18 on digram). I've searched everywhere and can't find exactly how it all goes together to make the horn work. If I assemble it as shown in this diagram, the biggest question is, where does the wire attach and does it need a different end put on it since the diagram shows it having an eye instead of a slider end? Before I took the wheel off of the parts truck, these pieces were assembled with number 5 on the bottom, then 3 with 4 inside of it so I don't know which way to go now. Any help is greatly appreciated. If you have pictures of how this goes it would help tremendously. Thank you.

 

this is really hard to explain over the internet and it not sitting in front of me, search youtube and see if someone dida video on it. there should be like a 4th hole for that wire to go into it. it should have like this little tab on it, it goes into the hole then twists a bit to stay in there
