I got the correct wiring diagram for my horn!

Yesterday I spent a couple hours building and testing the wiring diagrams for two different electrical relays, trying to figure out how to wire my Wolo Big Boy air horn. I was able to make the horn work on the bench but only using a switch with three terminals instead of the two terminals I have available. I just about gave up on the entire scheme and decided to just leave the horn powered through the switch like the stock setup.

I did find a "tech advice" email address on the instructions that came with my horn, so I decided, without much expectation, to give that a try. I sent off an email detailing my efforts and asked for advice or direction. To my extreme surprise, I received a response last night- it was Sunday, remember, and the email came in about 9PM. The person, Chris that responded directed me to their website and to the PDF instructions for a different model of horn. Those instructions have an entirely different method of connecting the multiple wires and I think they might just work!

I don't understand why there is such a disparity between the 2 diagrams but the second diagram says it is specifically for motorcycles so I am optimistic that I might get the horn wired up in a way that doesn't dim the headlights when I push the switch.

And that PSI carburetor I mentioned earlier that looked so interesting? It retails for $595! I don't think I will be springing for that upgrade on my little scooter anytime soon.

[UPDATE] No joy on the new wire diagram! Hoover Damm! I tried it tonight and have just about decided that the Wolo provided relay is Tango Uniform. I've requested a new one from the company. I did have success using one of the other relays I purchased, while working on the bench. So, I wrote down the connection numbers and proceeded to transfer the relay into the scooter. It doesn't work on the scooter! I'm busy on a schol paper so I really couldn't spend any more time and I put the scooter back together for another try another day.
