I must admit I have found that hard to work out too Dimbles. AS reliable maybe, but I can't see how they can be MORE reliable as I've never had any significant problems with a 7 pin. Nothing a screwdriver and/or a can of WD40 couldn't fix anyway. Like you I have towed all sorts of trailers, all fitted with 7pin plugs.

I have never used a 13pin set-up but from what I have heard they twist to lock in. I would have thought that could be a bit dodgy in event of a breakaway as it would rip the wires out rather than just pulling the plug out. Is this the case? If so, surely that's a fire risk?

My only slight concern is that if the 13pin plug locks in (and I'm not sure it does), what happens if there's a breakaway? I know that shouldn't happen, but it does. Would the wires rip out instead of the plug? If so, that could result in wires touching together and potentially starting a fire.

if the wiring has been done correctly, the fuse will blow with the current required therefore removing one of the requirements to start a fire.

Colin--the 13 pin uses a screw thread effect to draw the plug into the socket-only about 1/4 or 1/2 a turn is enough.It does lock in enough to prevent a straight pull out. I have experienced problems with the pins being bent on the 13 pin type and if you havent noticed can result in a few more bent pins--they are much thinner than the old 7 pin type.The 13 pin setup has the strength of the screwthread and the locking action of the socket lid to prevent a pullout so I personally think the cables would pull out of the connection block inside before the plug/socket joint gave up.

So has anybody had the wires pulled out of the caravan and snaking across the road?
I'm thinking that for this to happen you've probably lost your caravan so a few wires which have come lose would be the least of my worries!
