Hi what is the simplistic wirirng harness I can devise

[Jox]

Hi,
I have a VIP Future Champion 49cc GY6 1P39QMB, I was a Frankenstein scooter when I got it. I've got it resealed and and mechanically back together. I don't have any wiring attached yet. I don't have a dash on this scooter and I have no intention of installing one. So I'm really just going for headlights, taillight (brake light), and starting system. Do I need anything else to make this thing run from a wiring stand point? Anyone have any advice on wiring this bike to get it running? Any help will be greatly appreciated.
Thanks,
Jox
