7-pin ISO 1724 trailer connector type 12N (Towing vehicle side). This connector uses a mix of pin and socket terminals. Physical design according to standard ISO 1724. [4] [8] The 7-pin connector uses all 7 pins on newer trailers according to the ISO standard. [9] [10] On older trailers there's sometimes a 5-wire setup using a 7-pin connector.

If you have a trailer with a lot of lights the diode and relay wiring is preferred, but if you have a trailer with a simple light arrangement it is usually sufficient to wire to 58L. In market there are many special converters [ 1 ] [ 2 ] [ 3 ] that solves the problem of connecting a car with European wiring to a trailer with North American wiring.
The Type 2 connector is equipped with seven pin connectors, which are used for communication between the vehicle and charger using the J1772 signaling protocol, and for either single or 3-phase AC power with a maximum voltage of 500 V, thereby delivering up to 43 kW of power.
The 15 A 7-15 plug has the crowsfoot current carrying pins of the Type I plug, but with a U-shaped earth pin. The 7-20 version has an enlarged line/hot pin. 7-30 is a larger diameter connector, with an L-shaped neutral, while the 7-50 has an enlarged neutral pin, compared with the hot.
Note that the wire cross-section in mm² and AWG listed is the minimum recommended area. For ISO connectors the primary unit is in mm² and AWG has been obtained from a conversion table. For North American connectors the primary unit is AWG and mm² has been obtained from a conversion table. In both cases the figures are rounded up for cable area.
The image of the 7 and 12 pin flat plugs are from the cable entry view (and possibly the images of the round connectors too). Please see reference [2] (VSB1 section 14) for front image. Reference [1] Narva wiring diagrams also have the diagrams cable entry view. If you want the front view images in colour see [3]
Multicon [1] Feder and Multicon WeSt (Welt Standard) connectors are precursors to ISO 11446 in a design that is intended to be compatible with ISO 1724.This means that if a towing vehicle has an outlet of this type it should be able to connect a trailer with a standard 7-pin or 5-pin connector according to ISO 1724, provided that the trailer coupling follows the standard and that the trailer ...
