Kip, thanks for sharing the info. Like Bert, I've been trying to figure out how the dang thing works. I've got it all wired up and can honk the horn by completing the circuit with a screwdriver, but for the life of me I couldn't figure out how the horn button worked. Your explanation made it all clear. BTW, I got my cone unit from Obsolete Chevrolet Parts in Georgia if you need one.
