Does anyone have the wiring diagram for factory installed air conditioning? Can't find anything in the service book.

Yes, I do, but I would need to scan it 1st, and post it.

There is something in here, don't know if it will help you or not;

Yes that did help. Thank you.
I have a 55 Caribbean with factory air. Looks like is was installed by other than the factory. The air distribution box under the dash is correct but the hole cut in the firewall looks a little goofy. The dash control knob is a little off center. The oil filter was originally located on the right side of the engine and the air compressor on the right. I removed the compressor and moved the oil filter to the left side when I made up my mind several years ago I didn't want to bother with the expense of getting the air working. I also remove the air relay and have since lost it. I recall it looked like the same relay used for the horn. Now I think I want to re-install the air as it is unusual on a Caribbean.

Thanks again

Not the same relay as the horn but is the same type as the power window. If not too concerned about looks since it's under dash, modern such as thesehttp://www.parts-express.com/wizards/searchResults.cfm?searchFilter=relay%2012%20vdc and also available at most parts stores will work nicely. You should get one able to carry 30-40 amps.
