Electrical Help me find a missing connection

[Xavierg208]

I’m working on finishing up a rebuild that was unfinished and can’t seem to find where this pigtail connects to. It is located on the passenger side strut tower coming from the same harness as the MAF sensor. Any help is appreciated.

Edit: it is a 1991 mustang 5.0

If I had to guess it would be the O2 sensor connector. Would help to know what year car and a picture showing the color of the wires going into the connector.

Sorry got too ahead of myself. Original post is updated it’s a 91 mustang 5.0

What are the color of the wires going to the connector. That’s the only way to be sure what it’s for.

O2 sensor harness connector would be my guess based on location, but need to see wire colors

The HEGO harness, at least on my 88 5.0, is the only 8 pin connector on the engine. Mine is located at the back of the engine. Wire color will confirm.
