OK guys, I disconnected the connector to the monovalve and my A/C compressor would not turn on. Once I reconnected the monovalve connector, it started working again. Of course, my temperature control amp is still disconnected so I don't know if that had anything to do with it or not. I had a long day at work and don't have time to go back out and run through it again tonight, but tomorrow I will reconnect the temp control amp, then disconnect the monovalve to see if the compressor runs.

If we are having this much fun with our MB's, you got to wonder how the automatic A/C controls in "lesser" cars are going to perform in 20 years.
