Wiring?? WTB

[89GTconv]

Hey everyone.....
Im new to the site and thought I would see if the main problem I have with my car can be answered by those of you who know MUCH more than I do......Long story short, the dash wiring in my car is F-ed and I guess I need to just re-wire the whole thing. Anyone have the wiring or know where I can buy all new?? Thanks!
