Trailer connectors in Europe
A number of standards prevail in Europe for trailer connectors, the electrical connectors between vehicles and the trailers they tow that provide a means of control for the trailers.
7 and 13-pin connectors
[edit]The 13-pin (ISO 11446) version being phased in is newer, provides more services than the 7-pin (ISO 1724) , a more positive locking and also better protection against moisture and contamination.
- 7-pin connectors (ISO 1724)
- 13-pin connectors (ISO 11446)
NEN 6120—Connectors based on ISO 1724
[edit]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 plug casing is not made of metal since a metal plug will otherwise short the extra pins.
- 13-pin trailer connection of type Multicon Feder
- 13-pin trailer connection of type Multicon WeST
Both connectors have the same electrical wiring[2][3][4] and can be found primarily in the Netherlands and Germany.

The following supplementary information exists for the connector:
These connectors are specially developed by sv:Djurle Industri AB (DIAB) for severe conditions where snow, ice and salt are common. They can be equipped with an optional heating loop if necessary. Moreover, they are "self-disconnecting" to lower the risk of damage to the connector if the driver should forget to disconnect the plug when disconnecting the trailer or the trailer jumps off the hook.
The 14-pin, 17-pin and 22-pin connectors have the same physical dimensions, but different contact elements in the contacts.
These connectors occur primarily in Scandinavia, but vendors exist in the United States, Belgium and Great Britain, which means that they can be found outside Scandinavia as well.
Connections for these contacts listed as spare are free to use.
Maximum allowable current for ground contact is 25A.

This connector is designed for 12V electrical system where the standard ISO connectors are considered insufficient. The connector is designed in the same manner as the connectors for heavy vehicles, but is physically smaller.
