95' PF mystery ground

[N2mesnob]

I have a 95' SE Pathfinder...Ok so I was up under the hood of my baby the other weekend installing new bushings when I came across what I think is a grounding wire.It's connected to the body in the area between the intake filter and the windshield fluid tank.I have a missing bolt on the heat shield on my header and thought maybe it came from there except it does not reach that far.Than I thought it may be from the alternator but after talking to a few friends they say that my alternator would not work if that was so. And my baby runs jus fine. Also I don't believe it will reach.Than someone suggested that it may be for an option for the Pathfinder that was not equipped on my rig.All I know is that it goes to something, I don't know but would like to know what that something is.I don’t want to disconnect it if it has a use and would prefer it not to jus dangle there if it goes to something.Any ideas?
