Hi John

In reply to your PM...

Ottos link above looks correct - you need to check the second post in it - it's the 12n socket.

You have an eighth wire (Pink), this is probably for the fog-lights, so that they are cut-out on the car when a trailer is attached. Break the wire to the car fog-light and connect the pink wire to the feed and the blue wire to the car fog-lights. If the fog lights on the trailer don't work as expected, reverse these two connections.

It is normal for the car cables to be different colours, even between models by the same manufacturer, so cannot advise on those for your car. I used a Renault plug-in kit, so didn't need to trace the wires, but in the past have used the method suggested above - a test-lamp or meter is also a big help.
