Smoked wire behind dash ….!HELP

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 onsomething and a huge puff of smoke from behind my dash happened. I thought it was my stereo at first, but ended up notbeing a stereo on. It went all the way back to the fuse box Inside that wire loom. It also touchedand got hot obviously next to other wires so. Now I had dash lights after the wire head grounded out, but then theyflickered 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 havepulled 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 rearlocker lighting up when I haven’t even touched the button. I’m at a loss right now trying to figure thisout. It’s a 2006 Toyota Tacomapre-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 shoppress?
