XR7G fog light wiring harness

I am restoring my XR7G. During this process, I found a cut wire in my fog light harness. It doesn’t seem to effect anything as the fog lights work. I am guessing that it is a ground. I have attached a diagram of the wiring harness and have circled the portion that is missing. Does anyone know what this wire is for?

Thanks,
Mike

I think that is the ground.

here is the blue print for the harness: https://classiccougarcommunity.com/downloads/1968/XR7-G_blueprints/Wiring_Assy-Fog_Lamp.pdf

Any chance you could look at one of your cars and see what it is? It would be on the driver’s side.

Thanks,

Many of the Gs have a mystery wire around that area. I have found that when you turn on the fog lights at the fog light switch, that the marker lights come on, but at a dimmer state. I have had this on two of the three Gs I have owned. The other one, I don’t recall. I did not own it for a very long time.
