I kind of pieced things together from various sources, not sure I know of one in particular. The sticky in this forum about wire is a good, you need to learn about Ohm's law, you need to know about the different types of batteries and what you need. Everyone seems to have their preference on mesh, silica, ceramic, wire rope and types.
I think I actually learned how to wrap a genny from Scott (igetcha69) reviewing something. If you don't know the battery stuff, learn that first even though your evic is basically training wheels in that regard. I'll try to gather some links when I am done working.
