The best place for the heavy ground cable is right up there at the starter gen bracket. It's only one cable, not part of a "harness". I ran all my heavy cables in one bundle to/from the S/G and it looks pretty decent.

When you're rewiring, make sure the voltage regulator is grounded. It's on rubber mounts and sometimes there is a ground wire, and sometimes there isn't, across the rubber section.

Proper colored wires is a benefit, but there are only a few wires. I've used labels that are pretty much forever. Brady.

My 126 was wired positive ground when I took it apart. It all worked quite well, somehow. I still haven't figured out why.
