12-pole NATO trailer plug/socket:

(letters A-N, but without the use of the letters G and I (to avoid readability problems cq character confusion with C and J)

(note that this also explains the neverending confusion between the description '14-pin' vs '12-pin'!....8-))
(the *full* alphabetic range A-N contains 14 letters....;))

Not sure where 'Ground 1-8' stops, because 'Ground 9-13' means 13 pins, while there are only 12....8-))
(probably (mis)taken from the 13-pin civil layout!)

Also note that on some older German/Bundeswehr trailers/vehicles, D only means trailer-ground, not vehicle-ground.
(so you can check the trailer-plug on its own, but not the vehicle-socket!)
(this was meant to allow the vehicle-system to detect whether a trailer was present or not(?), 
modern vehicle-systems apparently do not need this signal)




Benefits of NATO-connector vs civil:

- soldered joints/wire-sockets (no corrosion, no rusted screws)

- waterproof sealed joints/wire-sockets (no fauling of connection)

- integrated hinged cap on both plug and socket, keeping dirt out
(UK-version can have separate rubber cap, attached with a cord)
