You're welcome! Yeah, too bad we weren't a little closer ... I'd gladly take a look at it for you.
In any case, I think you're on the right track with considering new wiring harnesses. That will give you a new fuse box, clean things up under the dash, and hopefully eliminate the short circuits, old repairs, etc. that are causing problems. I'd recommend either American Autowire (
www.americanautowire.com/) or M&H Electric Fabricators (
www.wiringharness.com/). They both offer a number of choices depending on how many modifications / updates you've added (or plan on adding).
