Why do you have 2 contact boxes and why not a single 13 pin? Is there a special reason.
Find it ugly too have two of those things under my bumper. even hate the 1 I have under my car.
I would like anyone on attacks but just curious.

For some strange reason, in the UK when we added the 12S socket years ago as rear fog lights were added to cars & nicked the feed from the 12N socket that used to be used for the caravan's fridge &/or charging, we seemed to stall & not progress from that. The 12S isn't the best of sockets either, it's not uncommon to find the pin suppyling the fridge to burn out. While continental Europe progressed and came up with (various

) 13 pin sockets we didn't & kept 2 sockets.
We are catching up though, all new caravans now come with a 13 pin plug.

I have upgraded both my car & caravan.
A couple of years ago in France I offered my help to a Dutch man who had ripped his socket from his car, it was 13 pin, but different from mine. It had the old style round 12N pins in the middle & had flat spade connectors around the edge, presumably for his caravan's charging & fridge.
