Bike restoration - 1975 Yamaha DT400 B

[Chippy 123]

I am calling on the BB crowd for some help with a bike restoration I'm currently working on....I'm struggling with the wiring and have been scowring the tinterweb for a color coded wiring diagram. As already stated the bike is a 1975 Yamaha DT400 B, the B is important to not confuse it with later models as I have discovered when sourcing spares. If anyone knows of any archives they could point me towards I would be really grateful .....thanks in advance
