Dean,i think for the most part your schematic looks good.I don't see a need for the additional blue + wire.I would install a terminal block and run all of my needed power off of that,except for the r/r.I ran one central ground to a nutsert welded on the lower part of my seat post(frame).I also used a 3-way on-off-on toggle switch mounted directly onto the headlight shell,this helps simplify the wiring a bit.I use 3 on-off toggle switches for taillight/tag(this wire also runs up to the headlight switch),one to my coil,and one to the R/R.After i start (kick only) it up,i then switch on my charging system and then the lights.I am running a small scooter battery,so at red lights i simply reach up and turn off my headlight so most of the battery juice is going to the coil.Everyone has their own preference,but this is simple(like me) and works well.Good luck!
