What are these connections? (1 Viewer)

I was putting my new ARB bumper on my LX470 and noticed these two pigtails in the very front left (driver side) of the truck. I searched but I could find these exact connections. One goes to a sensor which look like an Airbag sensor?

I believe that is the AC pressure switch, sight glass on the top if it is, disables the compressor clutch if theres a leak in the system and freon is low.
