Heres some info Dave, its actually pretty cut and dry. Im by no means a magical fabricator at all. I figured all this out myself in my backyard using hand tools and home depot hardware.
heres the diagram i made that shows you what to cut and where

heres a pic of the brackets that i bolted to the battery bracket

another from the back

Heres a pic of my wiring rerouted under the seat.

It looks complicated by its just basically taking all the wires and looping them around to fit under the seat and above where the battery hangs. If you look close you can see the solenoid that I have clamped to the top of the battery strap. And the fuse box doesnt need to be mounted anywhere because the main harness is pretty stiff and doesnt let it rattle around anywhere. In fact I like my fuse box like this because I used to blow fuses all the time from hard bumps. This was because my suspension is lowered alot and the fuses were hard mounted to the bike which caught alot of shock from hard bumps. Now that its free hanging I havent blown a fuse yet. Of course thats not a problem for most that arent lowered, I figured I'd mention it.
Also I didnt mount anything on the backside to act as a fender, the brackets and battery tray sorta do that job pretty well. In fact when i recently took the bracket off I barely had any road grime stuck on there, and its been about 2-3000 miles now.
heres some up close shot of both sides before I painted everything.
