Dave,
It sounds like that you have the same harness that I
used.  I didn't have a diagram, but it is only 7
wires.  I just checked them with an ohm meter to see
what went where.  Obviously 4 of them are the trigger
for each coil.  The other 3 are power (+12) and
ground.  I think that I marked the colors for the
harness on the diagram in my EC-2 manual.  I'm
traveling back home today, so I look and see if I
still have it.
