I took a trip and on arrival set up and strangely the water pump would not work.
I spent a day and half looking at alsorts but found in the end that a pin in the plug coming from the pump switch, behind the main control panel, had come loose.
Now during my investigations I removed and opened the 12v from car switching relay. All seemed to work.
Now all the 12v work, mains on hookup and road lights.
NOW.... school boy error. I would normally photo any connection before disconnecting, just so I know how to put back as was.... I didn't with the relay.
As said all is working but, now on the main control board the car/nothing/caravan switch is backward.
If I was to upload a pic of relay as is would someone advise which wire goes where? Or pass on a schematic?
Thanks all for the help so far.

The schematic you require is printed on the side of the relay, you can nearly see it in the second picture. It should show the two connections for the load (battery) and the coil (switch from car).
I believe it should be that if there is no 12V from the car then the load circuit should be closed ie 12V from your battery off to your distribution board.
On a 12V signal from the car then the battery is disconnected from the distribution board..... I think ;)
