Anex 570

I cannot figure out how to fix this wire and problem I have. The pink and blue wire that runs to the headlight switch melted the plastic off. I'm trying to chase it, but dont know where it ends up for sure. If I do get that done, I dont know if my brake lights will work like they're supose to, thats the initial problem that led me to fix the wire. If I were to take this to a garage what kind of price would I be looking at you think?
