Interior light wiring - Dormobile

[Porkpie]

Morning Everyone, It's been nice for the last few days so trying to tidy the wiring before fitting the dash back in. Does anyone know where the feed for the interior light switch comes from, I suppose its the top of the fuse box, but which fuse?

Thanks for any help.

Regards, Si

Thanks Trikky, I have read the normal wiring diagram but the terminals suggested for interior lights are already in use, so I was wondering where Dormobile took the feed from?
