vdo wiring loom

hey guys, looking for a little help. does anyone know where I can get a copy of the wiring drawings for the 3 vdo gauges. I've got 3 diff hanes manuals but can't find it in them.
 I bought this Lhasa green campaign (after my first one [red] had died) about 3 years ago after it had had a full nut & bolt rebuild, totally standard but needed little things finishing off, but due to a new job (motorway miles) I'm thinking about selling her so I want to sort out some of the things I was going to yesterday……
If anyone can help all I can say is big thanks and  I WILL make one up and fit it.
