So I thought I would modernize the ignition circuit diagram for the Model T, with this colour coded, computer generated version.
Feel free to download and print for your own reference.
It also includes full colour coding for each of the wires...

Nice work. Your diagram shows what the other diagrams do not. They all show the timer as this mysterious thing with 4 wires coming out of it but no source of power. Your diagram shows that it is grounded (thru the engine) and I would suggest adding the note that it is grounded thru the engine.
Well done! I'd suggest adding a line under "Engine rotates clockwise" that says "Timer rotates counter-clockwise."
LIKE! NOW LETS DO ONE OF THE HARNESS FOR MY 23 COUPE WITH STARTER! COLOR CODED OF COURSE.
Thanks for the suggestions everyone, all very good ones I might add
Ralph -- I have shown the timer grounded through the engine, hence the dotted line attached to the bottom of it (see explanation of conductors at top)
Peter -- Thats an excellent point! additionally I should clarify that the timer rotor (roller) is the part that rotates, as the timer itself only rotates partially for advance and retard ;)
What a great diagram! Thanks, Mitch! Cheers, Bill
