Good progress despite rainy weather - I spent better part of weekend and today battling a flu.

Photo #1 - I am not sure what that vacuum module is. I am guessing on this one, but it was used to monitor vacuum levels for cruise control system.

Photo #2 - looks like a cruse control module. It is a guess on my part.

Photo #3 - CS series Delco-Remy alternator. You have couple of options here. Since you have two wires going into the plug you have a self excited unit and only 'L" and 'I' terminal are connected to wire harness. You can get a replacement pig tail from most auto parts stores or cut the one that you have and wire it into existing harness. Only 'L' light circuit is required:

For more information regarding CS alternators look here:

It is a commercial site, but they provide good information. Or you can simply purchase an adapter harness for about $18 D1-W1201
