Wiring Meltdown

Although very embarassing to report when replacing my battery the other day I made the stupidest mistake of my back-yeard mechanic career. I reversed the neg and pos battery cables and smoked the wires to alterantor and starter (assumed that red battery cable was positive and black was negative which was dumb and dumber since the builder did not follow standard colors and I did not check).
Replacing the alternator and hopefully don't need a new starter as well. I am looking for a whone new harness but may have to replace individual wires one by one. Any comments on what else I may have damaged?
Thanks so much.

I would think the starter would be ok - reverse polarity fries transistors/diodes so if you have a radio and it was on or even had the memory feature it may be a paper weight (electronic or CD/transistorized ignition fried too). An alternator place can replace diodes in your alternator too cheaper than replacing entire unit. None of the harnesses (I know of) come with the heavy cables to battery. Dune buggy harnesses ($40) from JC Whitney would work but don't include gauge wiring. If just a few wires - and whole harness not melted together - I'd replace the burn ones and rebundle harness in the corregated black plastic split tubing.

I might worry about the gauges, too, if the ignition was turned on while it was reversed. Or an electronic ignition module (the coil should be OK).
