Need help with a wiring problem.

[mclemore102]

I just now got around to charging my a/c up for the first time. But my compressor doesn't kick on. Well i got to check for wires that might have been cut or unplugged and found this one unplugged. But i can't figure out where it goes? It runs into the same harness as the two plugs that attach to the blower. Does anyone know where it goes.

Goes into a sensor in the top of the Heater/AC box.
Toward the engine on top.
If you still have the foil heat shield it has a hole in it for the sensor.

Ok i know where it goes now. But i have a bigger problem. I replaced my hvac box when i fixed the car. The one i got was off a 01 grand marquis.It doesn't have the sensor or hole in it. So does anyone have a wiring diagram of this or can tell me what this sensor does? When i took mine apart awhile a go it didn't have anything in it so now am stuck.
