Where does this wire go? With pictures

[Stretch]

I found this wire unattached in the bay just above the battery area. It is a single small wire, looks like a ground. If anyone knows for sure, or can go outside and look and find out where it attaches to that would be greatly appreciated :icon_bigg It is the brown wire with blue end piece. It is screwed in a bolt, and another set of wires are around the same bolt under this wire, but not of the same set.

Looks like a simple aftermarket crimp connector to me. Someone probably used it as a ground for something. It looks like it has blue insulation on the actual connector. I think all of the OEM grounds are bare connectors.

Most automotive manufacturers don't insulate the barrels on ground wires. Probably keeps the cost per vehicle down by some small fraction.
