How did I miss this?

1) Are you absolutely certain no other wire is damaged in the harness? If one wire melted, the heat from it can easily damage any other wire touching it, shorting dozens of circuits. You don't want that. I'd pull some more of the lower dash and visually inspect as much as you can before going further.

2) The radio accessory wire (blue) also powers the clock, is your clock still working? If so, you can leg off that side of the circuit and bypass the original wire to the radio. If not, pull the fusebox as directed and find the side of the wire after the fuse, cut it off, then insulate it. Run a new wire from the fuse side of the box up through the dash to both the clock and the radio.

3) Lastly, I'm local to you and have a full dash harness from a 1995 SE manual that I can swap in for you if nothing else works.
