I was looking down my engine bay the other day and realised this blue wire that looks like isn’t connected to anything. Any idea what it could be?

Where does the other end go? If you had A/C that's where the compressor would be but I don't know if all cars came with the wiring in place.

It comes from the c101 wiring, hard to follow the exact wire, wouldn’t be from the oil pressure sensor below would it?
