I've been looking around:
So, you probably know it's a Lab-Craft, and it was original equipment in the early AutoSleeper conversion. Later on they moved to the CP4 model, which was badged as an AutoSleeper unit, before finalising with the MC2000.
I have not been able to find out any more, beyond what is contained in the
http://www.autosleeper.vwt25camper.info/index.html, but there is a user manual for the early models which at least tells you what each fuse is for.
I would use the relevant parts of the MC2000 stuff you have already found as a guide to what the wiring actually is
Do you have a specific problem ?
