I found a copy of the wiring diagram in a 1920 Dykes manual on line last night. The wiring diagram shows the tail/dash going to one terminal and head lights to another. I also see that the generator cutout is in the foot switch? If that is correct will save me from looking for it in other places. When and if I get this car, I will be getting some repair manuals for it. Right now the goal is to get it running and go from there.
Re the head light bulb; The chart is hard to read but what I have observed in most head light applications is that the filament in head light bulbs is V shaped. The 1157 is straight and would work to light up the lamp but more then likely will not give the light spread needed to be usable. If the V shaped filament is correct in this application, the other thing would be the orientation of the pins and filament. The pins can place the filament horizontal or vertical. One is correct, don't know which was used in these reflectors.
The bulb chart is on page 434;
