Thanks all, I should have Googled the part number. Not sure why the pics didn't show.

In addition to previous owner changes and deletions, I also am finding that the shop manual schematics do not match the car exactly. The A/C components do not appear on the main schematic. There have to be a switch and relay for the A/C clutch somewhere, or at least sockets where they used to be.

I'll take a clue from Frankenduster and check the other sections.
