Westfalia wiring diagrams?

[ArcticMatt]

Did Westfalia ever publish wiring diagrams for the leisure circuits? I'm wondering how easy it would be to fit a 240v hook-up switchover contactor like i've done in my UK T4 that detects if you are not on mains hook up and then switches over to an inverter (just bought one to fit next week). I based my set up like this diagram I found on the T4 forum:

Has anyone else tried this on the Westfailia's?
The contactor I bought was from Travelvolts.com:

Blimey. What essential service are you running that requires effectively a UPS?

It was handy on my other van. I only needed the one 240v socket rather than having one off each. Nowt flash plus I like wiring diagrams

I share your love of a good schematic.
I've got most of the leisure side stuff.
