I have 1919 Roadster than needs a proper wiring diagram. I'm attempting to make my own, but the differences from other non-starter cars makes it a bit confusing, as I have a steering wheel mounted horn/light switch and a coil box ignition as well, and I need better references. Any graphics will do.

I'm mainly confused about how the coil box ignition switch wires to the magneto and horn switch.

This is called a "Ford model t 1919 d023 ignition system" from Wikimedia. https://commons.wikimedia.org/wiki/File ... system.png
This may be helpful too.

Thank y'all, big help. I managed to figure out the rest of it.
