Wire behind dash in loom grounded out

So this should be interesting for all of you. I had a wire behind my dash in the wiring room ground out. Somehow it was a power wire, and it ground out on something and a huge puff of smoke from behind my dash happened. I thought it was my stereo at first, but ended up not being a stereo on. It went all the way back to the fuse box Inside that wire loom. It also touched and got hot obviously next to other wires so. Now I had dash lights after the wire head grounded out, but then they flickered once probably a week or two later and then shut off. I still have dummy lights, but no dash lights behind my speedometer in RPMs. I’ve tried tracking it down. I can’t seem to figure it out. I have pulled the pin from the fuse box connector so I could replace that but it just seems like it’s actually just a stereo wire. Is there any way to determine why my dash lights don’t work Also I’ve had intermittent issues with the rear locker lighting up when I haven’t even touched the button. I’m at a loss right now trying to figure this out. It’s a 2006 Toyota Tacoma pre-runner four-door 2 Wheel Dr. One other thing does anybody have a better way besides cutting The rear bearing out to replace it or is it only that tool and a shop press?
