4 Wire Trailer Wiring To 7 Pin

By | May 8, 2015



Securing a Safe and Efficient 4 Wire Trailer Wiring to 7 Pin Connection



No matter what kind of trailer you are connecting, the wiring is essential. If done improperly, it could lead to a myriad of issues that may not be easily detected at first, but have significant consequences down the road. In this article, we will be discussing the important steps to take when performing a 4 wire trailer wiring to 7 pin connection in order to ensure it is safe, efficient, and secure.

The setup process when connecting a trailer to a vehicle can be a complicated system of cables, wires, and connections. In some cases, the wiring may require an extra level of complexity depending on the type of trailer and the type of connection being made. For instance, most trailers require a four-wire connection when linking to a vehicle. However, if the trailer requires seven pins for functionality, then the entire wiring system needs to be upgraded to accommodate the added pins. In this article, we will take a closer look at the process of upgrading a four-wire trailer connection to a seven-pin connection.

Choosing the Right Equipment



Before attempting to link the trailer to a vehicle, the necessary equipment must first be acquired. This includes a connector kit, which contains all of the parts needed to connect the seven pins to the wiring harness. It is important to choose quality components that are designed for the particular type of trailer being connected. It is also important to ensure the components used are rated for the specific amperage needs of the trailer. Additionally, the appropriate tools are necessary for the job. These include wire cutters, crimpers, screwdrivers, and other small tools.

Understanding the Wiring Diagram



It is incredibly important to make sure the wiring harness is properly assembled and managed. If a mistake is made during assembly, it can lead to electrical problems that are far worse than any other potential issues that may occur. For this reason, a wiring diagram should be thoroughly reviewed and understood before attempting to perform a 4 wire trailer wiring to 7 pin connection. The diagram should provide an overview of the entire connection and identify each of the pins and the wiring colors and functions associated with them.

Firmly Attaching the Connectors



Once the proper equipment has been gathered and the wiring diagram has been studied, the task of actually connecting the pins and wires can begin. Each of the seven pins should be firmly attached to the wiring harness by crimping the connectors onto the wire with pliers or a crimp tool. Make sure to follow the wiring diagram directions exactly and ensure that the correct wires are connected to the correct pins.

Testing the Connection



After the wiring is complete, it is important to test the connection. Connect the trailer to the vehicle, power on the vehicle, and then activate the trailer's lights and blinkers. If any of the lights or signals do not function properly, it may be an indication that a wire was not correctly connected. If this occurs, it is advisable to disconnect the trailer and double check the wiring diagram. If everything functions correctly, then the connection is secure and ready for use.

Conclusion



Performing a 4 wire trailer wiring to 7 pin connection can seem like a daunting task at first, but with the right supplies and knowledge, it can be a relatively straightforward process. Having the right equipment and understanding the wiring diagram is essential for the safe and efficient completion of the job. After the wiring is complete, it is important to double check the connection by testing the lights and signaling functions. With these steps and precautions, the connection is likely to be secure and free of issues.
