HELP! What does this plug go to?

[Skarkull]

My car has been apart for some time and now I'm starting to put it back together. I was an idiot and disassembled it while angry and didn't label the plugs. I attached a photo, can anyone help me? It's on the driver's side, on the same loom as the cam position sensor. Thanks in advance.

a/c pressure sensor on the line from the condenser?

Yep that is exactly what it goes to. Thanks for your help!
