I am in the middle of that right now. I sold my original sofa and am replacing it with a 70" double reclining loveseat with a console in the middle. You are being generous when you call it a wire loom. My name for it is not repeatable in mixed company.
You can see mine here:

I have to relocate the DC distribution panel and converter assembly that was on the roadside end of my sofa so it is closer to the wall. I may have to disconnect all the
12V load wires from the breaker panel to do that, but maybe not. I haven't gotten far enough into it yet. I do know that the main battery negative cables are too short. I'll probably have to replace them as I don't want to splice in 3' more wire.
I'm going to take a
12 volt power supply so I can feed
12V to the thermostat and run the air conditioner but I'll disconnect the batteries and the converter so all the other
12V circuits will be dead. There is no shore power AC in that area, only 12V DC so my plan should keep me from getting electrocuted or setting the trailer on fire. As you can see in the second picture, I also have battery boxes to deal with. The base of my loveseat will be 11" off of the wall so I'm probably just going to rebuild what is there so that it isn't such a kluge. In fairness to Airstream, the flooring had been replaced when I bought the trailer so whoever did that probably did the shoddy job of installing the cover. The only vertical support for the edge of the top cover was a couple of 3/8" square sticks that were screwed into the top and the front cover. They were screwed to the floor with a couple of angle brackets. I'm going to put down a furring strip all the way across the floor and screw the front cover into that.
At least that is my plan until I get into it. They say a battle plan never survives first contact with the enemy.
By the way, the unterminated coils of wire are probably the solar panel wiring.
