The only thing not on your list that I can see is Pick-Up Sensors signaling Digiplexs. After everuything is powered up, the Pick-Up Sensors have to send a signal to the Digiplex Units to trigger the coils to fire.

It is possible to make a PUS tester with a .3v bulb and leads hooked to the PUS plugs. As the flywheel trigger passes by the PUS it collapses the internal field producing a minute electical signal. They can also be tested with an ocilliscope by viewing their sine wave pattern.
