AC replacement. Wire to compressor

I am not sure if the compressor wire is the one that comes out of the harness for the o2 senor harness or the from the front grill. There was some front end damaged repaired so i am not sure which wire it should be. I have atached photos. Please let me know. If this works i will start using on a regular basis and donating. I do a lot of my own mec work and run in to issues from time to time.
