not sure about what info you require but here is a little.

Have used one for 20,000 K of towing and find it very good with no problems at all. It is a very firm fit and nothing seems to break unlike the flat 7 pin one where the locking flap always seemed to let go.

The 7 pin plug will fit into the 12 pin receptacle which is very versatile.
Here is the wiring diagram.

There is no new style of trailer plug and socket, all have been around for years.

Most common is the large 7 pin, rectangle 12 pin and the rectangle 7 pin.

We use a different type of 7 plug for our trailers only because the way the plug and socket lock together and it's mega heavy duty.

Don't know about any new style connector, but there's a comprehensive listing of connectors and connections here on ExplorOz.

I don't know how "new" they are, but I've discovered that there are 3 types of "flat" trailer plug recepticals. (whether they be 7 or 12 pin). The first is the type discussed above. The next is a receptical with an internal reed switch, and lid with a magnet attached, with contacts normally open (there are 2 extra wires into the receptical). And then there is one with normally closed contacts. The type you use depends on the vehicle type.
I fitted a 12 pin flat receptical to my RG Colorado, and discovered that unless I fitted one with a reed switch having contacts normally closed, the vehicle computer threw up all sorts of errors about trailer lights and the car blinkers worked at double speed. Apparently, when the recptical lid is opened the light control expects to see a trailer/caravan attached, with added load of lights and indicators.

G'day John

Perhaps you're thinking of the magnetic type.

My research indicates they're quite expensive and perhaps hard to justify.
