Looks about like what I did to my charging system several years back as preventative maintenance. That Monitor wire from the factory goes through I think 8 Connects/Fuses/Switches routing through the ignition switch before It actually reaches the battery. When I tested the voltage drop across that wire from the R/R to the Battery I had some 1.2-1.3v dropped across the connectors, causing the R/R to step up that 1.2-1.3 volts to make up for what it thinks is a less charged battery than it really is, causing the R/R to overwork itself. My bike holds a perfect 14.3V all the time, no matter if I have high beams on, fan is on, heated grips, etc.
The only differences I did compared to your setup is I didn't fuse the monitor wire, since there is no amperage draw I didn't see a big reason to add anything that could cause voltage drop (Fuse). And I added new ground wires straight to the frame from the R/R, just because i could :P
Excellent work on your upgrade and pics!
PS: Does anyone know if the monitor wire was rerouted bypassing the ignition switch on the 06+? I haven't taken the time to look but if not it might be a good idea for the 6th 1/2 gens too.
