I have the three parts listed below to eliminate the battery on my 1978 xs650, but I'm unable to find any wiring diagrams to help determine wire that incorporates all these new components along with Front Lights, Brake Lights, Master Switch, etc.

1.) Boyer Bransden Micro Power Digital Ignition System Yamaha XS650 (SKU: 108-0076)
2.) Boyer Bransden Power Box 3 Phase Battery Eliminator (SKU: 108-0077)
3.) XSCharge XS650 Permanent Magnet Alternator Kit PMA (SKU: 108-0004)

Would the wiring diagram listed below be accurate enough to tie all these new parts into place along with lights & switches?

Reg/rect needs an earth.
 
New to me so I did some googling Not sure I read it right

These power boxes replace the voltage regulator, rectifier, and capacitor that is usually found in batteryless PMA systems, but provide the "ultra-clean" power delivery required by sensitive digital ignition advance units.

In the Schematic there is something that look as a battery and a Regulator But as I read it the power box contains all
Maybe I misunderstand something here
Not searched more but Boyer usually have instructions on their website
