Webasto wiring

[pcatterall]

Just trying to test a Webasto thermo top C which has come my way. The unit is new but has no loom, The loom outlet is fixed to heater body with no cable 'tail' for me to identify which cable is which.
Unlike Eberspacher it seems very difficult to get hold of wiring diagrams for Webasto heaters.
I have tried all the googled sites but there seems to be a bit of a 'closed shop' policy!!
Any ideas chaps??
Regards

Many thanks for this (and the usual charm in which it was delivered !!) .
I have seen that diagram, I have looked hard, that diagram only covers a small part of the wiring but thanks anyway.
