Vespa Kinetic CDI

The attached PDF is a wiring diagram for installing a Kinetic CDI onto a Vespa moped (Ciao, Bravo, Grande). It shows the bike with simplified wiring or hard wired. It should be a good place to start from and switches can always be added.
Here is a picture of the coils properly installed:
