Not completely sure where this cable in this 1st photo goes to but it looks like if you would spin the screw it would modify something. Am I wrong?

The 2nd photo... I think this is from the temperature switch? Is it ok that it's unplugged? If not or if so, why?

I appreciate the help! This forum is amazing!!!

I'm not sure about the first photo, what is it connected to?

The seconded photo is a pressure switch for the AC system, it won't let the compressor run unless you have sufficient pressure in the system. I assume your AC is not working?

The first photo is a vacuum line. The rubber end is plugged to avoid vacuum leaks.

Seems like the car originally came with vacuum adjustable European headlights (with the SLS rear suspension, this worked to level the headlight beam towards the road depending on load level) and when the US lights were put in, the vacuum line had to be plugged since the US lights do not have vacuum adjustment.

Yup, I see it now.

Ya my A/C is not working. Eventually, I'll tackle that issue.

if your a/c is working, then it has no safety for low pressure, or any option for aux fan other than always on.

Yes, that is the roller switch that controls the aiming of the headlights. My Euro 190D has one pretty similar.

Second pic looks like the pigtails on the AC high pressure switch. If so, shorting the connectors will engage the auxiliary radiator fan.
