iTrader: (2)

ive been trying to figure out why the SS blows tail light fuses right away. Found water in the tail light (car usually sits for weeks at a time so didnt know til i drove it). I drained the water and it still blew the fuse. pulled the gauge cluster and found a horribly burned wire and traced it back to the tail light fuse/ headlight switch. problem i have is, from the tail light switch there are two brown wires...then whoever owned the car before did their own wireing and those 2 wires turn into 8... does anyone have any idea how this wiring is supposed to be or have diagrams?? i basically need to know where the wires all go and if there is supposed to be 8 there.
