The trailer connector (trailer cable) systems include plugs, sockets and cables. According to more than 25 different international standards, trailer connector is used all kinds of vehicles. These range from agricultural machinery to cars and commercial vehicles to defense.
Euro Trailer Connector
According to Wikipedia, in Europe, both 7-pin and 13-pin are common. The 13-pin version being phased in, provides more services than the 7-pin, with a more positive locking and also better protection against moisture and contamination.
The connectors are designed for 12V systems. Exceptions for the 7-pin connector may exist where they may be used for 6V and 24V.
Vehicles and trailers with 6V systems can use the 7-pin or a 5-pin connector. Heavy trucks that may have 12V systems are usually older (vintage vehicles) or on non-European markets.
The color coding is defined in ISO 4141-3, but the standard color codes are not always followed and may be different for a particular vehicle.
North America Standard
In North America a number of standards prevail , or parts of it, for trailer connectors, the electrical connectors between vehicles and the trailers they tow that provide a means of control for the trailers.
Australian Trailer Connector
The Australian market uses its own version of especially the European contacts, but also completely own contacts.
The only connector used in Australia that is fully ISO standard conformant is the 7-pin ABS / EBS plug.
Since Australia has vehicles from both the North American market and the European market, there is a mixture of 12V and 24V.
