Japanese Automotive wiring colour codes.

[Ocky]

I've been searching online for Japanese wiring colour codes.
I'm grafting a powered pop top roof from a Mazda Bongo onto a Toyota Hi Ace van and cannot even find out if all Jap vehicles share the same colour codes on the wiring ?
I could do with a colour chart like an excellent one I have for British cars by Lucas.

Can anyone help?

All the best, Ocky.

I did some googling, and managed to find this: https://www.the12volt.com/installbay/vehicles.html - could be a useful resource, but doesn't answer the question at hand - The search continues!
