How to install a pin connector on your trailer

Pin connectors for trailers are an essential component that should always be installed, as they supply the necessary electricity for the trailer's lights to function. Given their importance, it is essential to know how to install them correctly. In this article, we will highlight the different models of pin connectors available on the market.

Types of Trailer Connectors

The classification of connectors is based on the number of pins they include. These pins refer to the number of connections they can make with the trailer lights. There are two types of connectors for trailers: 7-pin and 13-pin.

The most commonly used model is the 7-pin connector, as it fulfills the basic connections required by any trailer. On the other hand, the 13-pin connector is used when a greater number of connections is necessary.

7-pin Connector

The diagram of a 7-pin trailer connector is as follows:

The connections for the turn signals are 1 for the left and 4 for the right. For the position lights, connections 5 and 7 are used, with 5 for the right side and 7 for the left side, while 6 is connected to the brake lights. Finally, 2 and 3 are the positive and negative connections, respectively, and 2 is also used for the reverse lights.

13-pin Connector

Although the 13-pin connector is used for caravans or large trailers, it is advisable to know what each pin means in case it is needed.

Connections 1 to 7 perform the same functions as in the 7-pin connector, except for number 2, which is used for the rear fog lights. Focusing on the different connections, 8 is used for reverse lights. 9 and 10 provide a constant +12V power supply, while 11 and 13 are the ground wires for connections 9 and 10. Finally, 12 is only used when the other connections are insufficient.

How to Install the Pin Connector for Your Trailer

Once the function of each pin is known, you can begin installing the connector. This task is not complicated, but it is important to do it correctly to avoid any issues. The steps to correctly install the pin connector for a trailer are:

• Strip the wires and remove the safety nut from the connector to open it in half.
• Unscrew the connection points of the connector and pass the wires through the safety nut.
• Connect and screw the wires to their corresponding pin. You can use the wire color as a guide.
• Once the wires are connected and securely tightened, you can join the two parts and adjust the safety nut to close the connector.

As you can see, installing the pin connector for a trailer is very simple. However, if you encounter any problems during the process, do not hesitate to contact a professional.
