What the heck is this wire?

Two weeks ago during heavy rain fall my car would not start. I checked the battery and it was good. looking around don't see any thing out of the ordinary, out of curiosity, I unplugged this wire then my car started, plug it back in, car won't start, so I left it unplugged.
anyone know where this wire goes to or what it does? it looks like it goes into the inside of the rear bumper, I don't have PDC.
