A good start is to hook your yellow from the CDI to that double red. That should get you head and tail light. Hooking up the brakelight circuit is going to be more difficult. Just get the headlight and tail going first.
Do you have a way to test bulbs to tell if they are any good.
Also if your headlight is the stock 6v sealed beam I dont recommend using it with the lapartie at full riding RPM with out a voltage regulator. It will pop.
It's ok for just doing your wiring at an idle though.
Do these tasks and check back.
