Default 1989 Wiring Harness Removal

Hello all. I have a 1989 Cherokee Limited. I need to remove the main wiring harness that runs from under the dash and through the firewall. The horn wasn't working and I was hearing a buzzing from by the fuse block when pressing. While pressing the horn to try and figure out the noise, smoke came from under the dash. I removed the negative terminal and investigated further. The horn relay and wires melted and of course they run right through the middle of that harness. The insulation is melted on those wires as far as I can see. Now, the horn is on as soon as I have key on. I've removed the 2 screws from the fuse block, but it doesn't seem to want to come out. It appears that it's connected to 2 harness plugs on the engine side of the firewall. I'm afraid to break it trying to pull it out. What am I missing? I don't see any other screws. I have done extensive searching to no avail. I've been able to find everything else I've needed here, so this is my first post. Thanks in advance.

That's kind of what it felt like. I can't even get the harness to unplug from that side. I'll see if I can get a driver in there. Thank you.

Does that bolt also retain the wiring harness junctions? I can't seem to get a driver in there and still can't remove the junctions.

I don't suppose you want moral support?

Yes, thank you. There was another bolt right in the middle of the harness on the engine side. Several choice words, a rigged chuck with ratcheting wrench and about 500 clicks later, it finally came out.
