Hey all! I'm going to head this as short and sweet as possible.

I'm in the process of repairing my old 82 Suzuki and the stock wiring harness is shot from the previous owner. Making the bike into a cafe racer, so I'm making a new simplified harness.

The issue I'm having with the wiring diagram is how to wire the CDI box properly for spark.

The diagram (shown above) shows 7 wires coming from the CDI box.

Black-> Frame ground
L (Blue) and Dark green-> Signal Generator
White and Black/Yellow-> Respective coils
Orange/White-> Coil power
and lastly Black/White ->???

My main questions are if the Black (which is not a wire that comes from the harness) is the frame ground from the metal back plate and whether or not the Black/White is a hot power wire to a fuse or a different ground.

The bike has brand new coils, spark plugs wires, and plugs but I have yet to get a spark. Any information to keep would be greatly appreciated. Thank you.
