Hi all. I'm in the process of wiring up my 46 Chevy 2-ton and am now at the the horn. When I bought this truck, it had a single trumpet-style horn mounted to the core-support brace on the passenger side. You can see it here.

It grounds itself to the support rod and used a single hot-wire from a generic push-button mounted on the side of the steering column.

My question is: Is there any way to operate this horn using the stock horn button?

I'm still trying to wrap my head around the stock horn operation as it seems kinda bass akwards to what I'm familiar with.
