Welcome to the forum.
Being that the main harness routing hole through the frame webbing is on the right side, the routing is generally right side.
If you run it through and drape it over the main tube up front, the sub-harnesses basically fall into place, with the exception of the section that feeds the rectifier, start capacitor and other stuff in the battery area.
There are several member project build threads that have some close-ups that you can study, you just need to search back.
