I've been trying George, but so far I haven't gotten any information on
what connector might fit.  The D581 is smaller, from the photos it
looks like it mounts to a flat surface, and it costs less.  The only
advantage I see to the D580 is I know what connector fits. :)

I did find the following information from a Google search.  On June 13,
2004, Mark told Ed A. that the connector he was using with his D581
coils was GM p/n 12126487 or AC/Delco PT757, but it needed to be
modified slightly to work.  GM Parts Direct wants $21 for the
connector.  Unless we can figure out what connector that is, it makes
the total cost for the D581 coil and connector about $46, and for the
D580 $36.  -- Thanks Mark
