On my quest to clean up engine bay I cut snip relocated things and finally last night I thought all done.
Until the final inspection and I found a loose wire and no written tab to go along. Cant figure out what this sucker was plugged to.

1995 gsx driver kick panel fusebox..unmount it and on reverside (back)
On the top there is a yellowish plug.
The 4th pin from left to right is a thicker gauged black wire with white stripe going down it. Pretty long too so not even sure where I would have snipped it.
Could it be a ground?
