Just a suggestion -
It would seem to me that if you have the harness, going through it and replacing the bad stuff, rewrapping it and repairing connectors at the ends might be a lot easier than a full new replacement.
That way you ought to be able to match lengths, etc.
There's a lot of wiring diagrams if you search Pantera Place, or if you join POCA and get access to their technical library.
Good Luck
