The existing harness has been repaired in several places, meaning it has wires that were melted and replaced with new sections. I am having the common no.4 guage fuse blowing problem. I have determined that the short to ground is in a huge pink wire that is one of the two wires going to the no.4 fuse on the terminal. That wire has been spliced just as it comes out of the firewall connector junction. If I can just replace this harness with another one I will. The local dealer said that the harness has been discontinued.
