How does a European style trailer connector differ from other types of trailer connectors?

A European style trailer connector, also known as a Euro-style connector or ISO 1724 connector, differs from other types of trailer connectors, particularly the North American style connector (commonly known as a 7-pin connector or RV-style connector), in several ways. Here are the key differences:
Number of Pins: The European style trailer connector typically has 13 pins, whereas the North American style connector has 7 pins. The additional pins in the European style connector allow for more functions and capabilities.
Functionality: The European style connector offers a broader range of functions and capabilities compared to the North American style connector. It accommodates various electrical connections for lighting, signaling, braking, power supply, and other auxiliary functions. The additional pins in the European style connector enable the connection of features such as reverse lights, fog lights, and additional power circuits.
Wiring Configuration: The pin configuration and wiring layout differ between the two connectors. The European style connector follows a standardized wiring configuration defined by the ISO 1724 standard. Each pin in the European style connector is assigned a specific function, and the wiring follows a consistent pattern across vehicles and trailers using this connector.
Physical Design: The European style trailer connector has a different physical design compared to the North American style connector. The European style connector typically consists of a round or rectangular socket with the pins arranged in a circular or rectangular pattern. In contrast, the North American style connector is a larger, rectangular cnnector with pins arranged in a straight line or semi-circular pattern.
Regional Compatibility: The European style connector is more commonly used in Europe and other regions that follow the ISO 1724 standard. It is designed to be compatible with European vehicles and trailers. On the other hand, the North American style connector is predominantly used in North America and is designed to be compatible with vehicles and trailers in that region.
