Electrics help? Rear door linkage

My rear wiper, rear dimister, rear fog don't work?
I have replaced the wiper motor and the fog light bulb, still nothing. All electrics in the door and in the light cluster look fine, is there any way of identifying which wires link to these near the fuses and switches under the driver console?
i.e - Do land rover have a guide to which coloured wires / plugs connect to what?
As my landie has loads of cables that seem to be disconnected (and I mean loads, 7 or 8 different cable looms are not connected).

sounds like an earth fault, check all the earth wires you can get to, make sure they are tight and theres no corrosion on the connections.

Us lot at dealers do have wiring diagrams, the next best thing would be a haynes manual or look on ebay for workshop manuals on CD.

im no expert on disco's but you have to admit that if 3 things on your rear door dont work , the only conclusion is a common part, ie ground or earth connections, run a temporary lead down from your battery to a bolt on the door and see if that cures the problem, you may find oxidation or rust on your hinges etc causing poor connections

to follow up:

i checked for earthing issues, in the end it turns out that someone has had the dash off in the past and muddled wires around, so i was getting very strange results... took half a day just to get all the wires sorted.
