Wire melted... tail light and dash light is out.

[TSI_G_FORCE]

yesterday my 92 talon lights went out. i mean the tail light and the dash light went out. i tried putting a new fuse and even a big fuse in and the problem got worst. the wire where you put the tail light fuse in, all melted. melted throught the rubber and the black wireing tape. it's the black box in the engine bay to the middle left. that fuse box there. if you take off the fuse console (there are three screws holding on to it) and look under it, there will be a red wire and that is the one thats melted. the wire is still there but i dont know why or i can't figure why that happened. please post up anything that can help me.
