Vito campervan w638 Japanese import wiring diagrams

[JillH]

Hi, I have a Vito van conversion with lots of problems - the garage are looking for wiring diagrams to try and sort the electrics.

Its a Japanese import W638 1999. Its had a new ECU but there are still electrical problems. Does anyone have any advice about where to find Japanese wiring diagrams - there's loads for European models out there but cant find any for a Japanese model.

Really appreciate it if anyone could help..

Thanks
