I aquired on a week ago with most of the wiring missing. It works fine now. Except the horn. Looks like there is a place for a D cell. I have the relay and horn. I need to know where to mount the horn and I need a schematic of the wiring. Where canI find these?

The B&O SSS set did not have a horn.

You can add the horn equipment as it was installed in the 400 & 404.

Schematic, pictorial diagrams, & parts list here.

Thanks for the information. It is exactly what I needed.
