I am working on wiring my cb750f project bike so that it will run and found this on the shoc4 site and have found it to be very useful as in which wires I can just set aside and which ones I really need. This is much easier that looking at those diagrams so I figured I would share it over here.
Heres a general list for the SOHC/4s (Consult your manual for specifics):
