What is this wire?

[VitaminC914]

84 FJ60-I found this wire over the inside of the rear passenger side fender. It goes down towards the wheel well covered in the plastic loom, but no loom as it goes through the body. Any idea what it is?

Thanks in advance!

I believe that’s power to the license plate light.

@Bullzi saw this thread and told me it’s the wire for the courtesy light switch in the rear passenger door. That happens to be the only courtesy light switch that doesn’t work on my truck so I might be working on this wire soon.
