Hi,
Is this the "camping" electrics or the "vehicle" electrics (or both!)?
If it's the camper stuff, then it'd be useful to have some information on which type of conversion it is, and any brand names on the switchgear (eg Zig).
If it helps at all, my Noppo conversion has a single switch on the dash that turns all the camper electrics on & off and a seperate panel in the back with individual rocker switches for the fridge, fans, lights, pump etc. The labels for these were in Japanese but someone has marked them up with translations.
The vehicle electrics should be pretty standard- my one is based on a pretty low-spec vehicle, so there aren't very many accessories to control... Yours may well have more features! If you can summarise what's unclear, I expect that there will be people here who can explain.
Welcome to the board!
Cheers,
W.
