Only can find about 6-7” of melted wire would I be able to reinsulate the wire and continue to use it?

That's a tough call, I think that I would be checking junk yards for a pigtail to use.

I'm not sure but a gas trucks wiring should also work.

Taping it up might get you back on the road but I don't know for how long. I would splice in some good wire instead of trying to re insulate it.

The problem isn't the melted insulation you can see - it's the melted insulation you CAN'T see, inside the harness. It's possible that the wires melted into OTHER wires, and are shorting to them (or will soon, creating a "cascade failure", and possibly another fire). The only safe move is to pull the dash, unwrap the harness, and repair it ALL. It's not as hard as it sounds, but it IS some work. I'm about to do it to my '97 because the dash shell is shattered. I've already pulled this one, stripped, & painted it:

The hot wire for the BOO comes from the dash fuse panel. Its output wire goes to (among other things) the MFS (turn signal switch), trailer brake controller, PCM...

This is a dash harness:
