Changed out Radiator

I changed out the radiator on my 97 GTP that sprang a leak. Took the cooling fans off, pulled the battery, and put the new one back in. Everything seems to work fine but while checking for leaks. I noticed a loose electrical plug I traced the wire back to the air conditioning compressor but that already has a plug plugged in. I was wondering does anybody know where this electrical plug goes that is split off of the air conditioning compressor plug wire? The wires are brown and black to the plug.

The coolant level sensor is located in the passenger side radiator tank which is close to the a/c compressor. Did you plug it back in?

Yep: That's plugged in. This wire is hanging down by the trans coolant lines at the base of the radiator. Instead of brown and black the wires might be tan and black. Looks like their are split off from the AC Compressor plug in wire. Thanks for you're help.
