Yes,  The hot neutral and ground are connected to the AC socket.  Another
cord then plugs in there to the power resitors, cap, and HEI coil.  This
allows the control box to be used for many other things.

The AC outlet comes with two standard socket on it.  There is only one
orange AC cord coming into the box.  It is coiled and twisted but it only
enters once through a conduit clamp in the upper left.

I was going to put the ignition coil ciruit close to the coil and gap and
then run a long cord back to this controller.  Since things are
experimental, I chose to separte things out this way.  I am a little
concerned about the high voltage from the primary cap getting into the
circuit and "lighting it up"  thus I am providing multiple grounds,
multiple MOVs, and multiple points is isolation.  In time, these may not be
shown not to be needed, but since it is experimental, I threw in everything...

When things are a bit more sorted out, a person has offered to help with
the art work showing how things go together.

Cheers,

	Terry
