Thermostat Temp sensor (on top) wiring harness help

My top sensor is unplugged and has been for years, car operates fine as does the A/C (well until my compressor just went out).

I'm planning on doing some AC revamp, and would like to get this connected, but cannot locate the plug or wires for this sensor.

Does the pigtail for this come from the same wire bundle as the o2 and lower Thermostat sensors? If so, what color wires are they?

Yes it does. Don't have the wire colors handy, but can look for them later if no one else gets them first.
