Not sure how I swap this out.

Yep, that's exactly where I was going. And the frustrating thing is that the wire is probably stapled down to studs along the way. If it was just fished through various openings, you might be able to fish new wire through by connecting it to the old.

I have no experience with trying to replace wire like you're talking about.

Do you have access to the ceiling above? Maybe you could get up in the attic and run new wire from above down to the two spots? Drill a hole above where the FP connects, and feed wire down into the wall. Drill a hole above where the other end of the wire connects to the circuit and feed the wire down to that location and the wire runs through the attic. That seems like the easiest way compared to getting access behind drywall all of the way between the two locations.

Hopefully, someone with a genius idea will come along with a suggestion.
