Help! 12S Caravan socket on Series II Disco!

Hello there,

Please can someone help with a few questions relating to 12S caravan sockets. I am totally confused.

There is a 12S kit for the Series 2 Disco STC50180. From the Rave disk it only appears to have two connections, green & yellow ( + earth) into the loom behind the offside light cluster.

From what I have read on the net, the wiring config. changed for 12S sockets from around 1999, as the internal caravan wiring systems were changed. As my caravan is a brand new 2006 model, I assume I will need to wire the socket to suit the later configuration.
As far as I can establish, the fridge supply needs to be live only when the engine is running,connected to pin 6 of the 12S socket & earthed through pin7. A permanent 12 v feed is connected to pin 4 & all earths on the van, other than the fridge return to pin 3. Pin 1 is for a reversing light.

If this is the case, then which two feeds are the green & yellow wires in STC50180 providing? I was going to buy an STC50180 kit, or make one myself & tap into the connection points shown on the loom, but before I do this I want to make sure I have the right connections.

As I see it I need :

12v permanent live.
12V live for fridge only when engine is running.
12v live for reversing light.

Finding a permanent live & a feed from the reversing light on the disco will be easy, but what have people done for the 12V switched supply?

Anyone been here before?

Thanks,
Tony

I havent had any experience in UK Landrover bits, but having fitted tow bars and wiring for many years, taking wires from just anywhere is a bit of a gamble especially if there is some fancy wiring systems. On the older vehicles it was a simple matter of tapping into a wire in the steering column with a circuit tester that illuminated when the ignition was turned on for your switched power. A feed on the input side of the fuse panel was always a good spot for a permanent power source, but needed a fuse in the line, and as for the yellow and green wires, they were always left and right indicator wires. Of course, trailers are still wired that way here in Australia, but not sure if its the same over there.
