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
