I hooked up the gauges and they read well above cutoff. The aux fan now (after replacing the aux fan relay fuse) comes on immediately upon turning the key, and stays on. I was able to get the compressor to come on briefly by bypassing the red pressure switch. Does that indicate that I have too much of a charge in the system? Also, shouldn't the fan go off while bypassed? Or is it the opposite? I'm doing my best to follow the MB troubleshooting guides, but a lot of it seems to be different in my model year.
Also, attached is a photo of another lonely connector I found. It's under the intake manifold, and I can't get a good look of where it's headed.
