So I'm helping a friend try to figure out the wiring on his 1980 (maybe an 81. The VIN and reg say 2 different things) Euro spec P125x with keyed ignition, 12v battery, CDI ignition, and indicators, and have run into some wiring questions. I've looked at a bunch of posts here and looked at these wiring diagrams, but some stuff doesn't match up.

The first diagram shows an engine junction box. The second shows a Ducati CDI, but with no engine junction box. Well he has the Ducati CDI AND an engine junction box. Has anyone ever seen this before?

Also, both diagrams show a junction box under the horn cast, but his bike doesn't have that junction box.

Anyone seen this before or have any ideas wtf I'm looking at?

A few photos of the scooter would help. It could also be a 6V points circuit. Don’t count so much on scooterhelp’s VIN info. My P’s VIN and year is also wrong on scooterhelp...

It should have this under the Horncast:

And without:

This is the CDI and Junction box it should have, if it were stock. The 125 came with points (I think, so no junction box unless the bike is retrofitted).
