The American style trailer connector is an electrical connection

The American style trailer connector is an electrical connection that enables the driver of a towing vehicle to control the trailer's lights. It is also used to power the trailer's brakes. These types of connectors are available in a number of different models and types. They are typically standardized to fit any compatible trailer.

The most common type of trailer connector is the seven-way plug. This model has two pins on each side and provides power to the trailer. It is often used to tow heavy-duty cargo trailers and enclosed car haulers. There are also round and flat versions of this connector. The round versions are usually used for horse trailers and horse trailer lights. Flat versions are more often found in towed vehicles.

One variant of the seven-way plug has a ground wire. The ground wire is usually white. It should be grounded at the tongue of the trailer. If the wiring is loose, the taillights may go out on the trailer. Another variant has an extra wire tapped into the backup lights. When the trailer's brakes are engaged, the additional wire disengages the brakes.

In Europe, the 7-pin connector is a common one. It may also be used for 6V and 24V. In addition, it offers better protection against moisture. However, some vehicles may have a thirteen-pin version of this connector. In these cases, the center pin is changed from a socket to a pin. Also, the number of pins on a thirteen-pin connector has decreased from eight to six. Moreover, some newer models may have a 13-pin ISO 11446 connector.

Another popular connector is the five-pin connector. It is a similar design to the 7-pin ISO 1724 connector, but it does not include the CAN bus pins. This is mainly common on trailers with electric brakes. Nevertheless, this version of the connector may not be powered by the towing vehicle after 1999. The fifth-pin connector is also commonly seen on vintage vehicles.

In North America, a number of different standards apply for the wiring of trailers. These standards include SAE J560. A standard that is designed for towing heavy-duty vehicles, it is standardized to use with a wide range of different trailers.

On the other hand, the 12N connector is used in Great Britain and other parts of Europe. In these regions, the center pin has changed to a socket. Despite these differences, this style of connector has been accepted in many areas. Besides being used for trailers, it is often used in caravans and other vehicles with a separate lighting circuit.

Many European trailers have an electric brake system. To connect an electronic brake controller to the trailer, an adapter harness is needed. Fortunately, this adapter harness is also compatible with the 7-pin version of the American style trailer connector. This adapter is known as the Nilight Heavy Duty 7-Way Inline Trailer Plug. It is a weatherproof, zip-tied connector that has a seven-gang junction box.

When it comes to towing a trailer, the most important thing is to ensure that the wiring is complete and in good condition. Incorrect wiring can cause the lights to fail or the electric brakes to malfunction. Luckily, there are a few solutions to this problem. Some of them include replacing the wiring on the trailer, installing custom wiring, or using a splice-in wiring kit.
