All I did was accumulate the parts.  My plan would have been minimal
splicing - ie, swap as many harnesses as possible.  When I did the dash
swap, of course, I had to splice all forty or so wires...

I repeat, you want more thna just the later fusebox, you *want* the
harnesses, they are much better.  Ever look at the evolution of those
little "AMP" connectors they use?  1st gen, nasty little things you need
a pick to separate.  2nd/3rd gen, they acquire a different lock that is
easy to undo, *and* internal seals so they stay clean.  And so on and so
forth... the later wires have nicer, thinner insulation, so they take up
a little less space...
