Maybe a repost, but found this while searching for non-Toyota wiring diagrams.

But Toys are there, too!

If you know Russian, go to http://www.autolib.diakom.ru/CARS2/

or if you want, us an online translator...
Worldlingo was the only one I could get to translate the whole page.

For example, I was needing the starter wiring diagrams for a BMW - here's how to get there:

Click on BMW
Then the third bullet down which gives 3 more sub bullets - go for the second one down.
A drop down menu should appear - choose your year.
Another drop down - choose your model.
Another dropdown - choose System Wiring Diagrams - and now it's in English - great eh!
