wiring from door locks to - where???

I think I may have exhausted this topic on the general forum, but maybe some of you sparkies are lurking around in here... I have wires going from all the door locks, they are complete i.e. they never passed through "actuators", they just went direct from locks to a central "brain". I got hold of a VDO central locking pump, which came off another G. The bloke who sold it said it was fitted in the driver's locker on his, though I now know that this wasn't original spec. for G wagen So I need to trace the wiring from the doors through the dash (this is where I lose it) and thus fit my new gadget. For the full story have a look at my earlier postings, including a photo of what I've got, iof that's the kind of thing you're into. It's not the end of the world as the VDO pump only cost me a fiver, but I'd like to get it working if I can, so any help gratefully received. Thanks, Glyn.
