Default Unconnected wire Engine Compartment 1992

I have a wire which is not connected to anything on my 1992 F150 XLT 5.0, 2WD, Automatic . It appears like it was as it has dielectric grease on the connectors. It comes out of the harness at the power steering reservoir. Can anyone tell me what this is or is just an extra? See the pictures.

From the looks of it (and I may be wrong) you may have had some AC work done in the past and deleted a sensor located on the inbound freon to the AC Compressor. Just my guess after taking a gander at my 94 5.0 engine bay. From the local of your lost plug it looks a lot like the one that is connected to the sensor/valve of some sort located behind my AC Compressor. Thats my story and Im stickn to it!

Thank you for your help. At this point, I won't worry about it.
