I was not sure if the starter switch was completely wired, or did I need to run any wires from the starter relay or master relay to it, so I took some high-res photos of the back of it to check the existing wiring. I believe that all remaining wiring will be terminated at the P-1 terminal connection.
I made the P-lead for the left magneto by following the diagram on the OP-10 drawing. I made a few mistakes, which were cut off, but the final result should work.
