Please help a golf buggy newbie out

[Hadden]

Hi all, new on here after purchasing what I this is a Yamaha g2-g9. Love anything with an engine and normally there isn't a lot that I can't bring back to life.. Problem I have is the wiring is in a right state. From research I have done it is all there but like said it's a mess. There about 8 wires not connected to anything, half of them I'm sure are earths but I'm struggling to find an accurate wiring diagram for it..it's a 285cc 4 stroke 8.5hp Yamaha engine.. That's all I know up to now.. If anyone could help I would be extremely grateful as I hate to lose to a non starter. Thankyou in advance,james
