If you’ve ever had the need to tow a trailer with your vehicle, you’ve likely encountered a 6 pin trailer plug. This type of trailer plug is most commonly used in Europe and the U.K., and can be used for a variety of purposes, from hauling boats and campers to transporting livestock and other cargo. Wiring a 6 pin trailer plug is not difficult, but it does require some specialized knowledge. Fortunately, we’ve put together this step-by-step guide to help you get the job done quickly and safely.

Step 1: Gather Your Supplies

Before you begin, you will need to gather the necessary supplies. Most 6 pin trailer plugs are wired the same, so you will need the following: a set of wire strippers, a pair of pliers, a soldering iron, electrical tape, and a 6 pin trailer plug. You may also want to have a multimeter handy to check the continuity of your wiring.

Step 2: Strip and Connect the Wires

Once you have your supplies, you can begin wiring your 6 pin trailer plug. First, you will need to strip the ends of the wires using the wire strippers. Then, connect the wires to the corresponding terminals on the 6 pin trailer plug. Make sure the connections are secure and the wires are not crossed or twisted. You may also want to solder the connections for added security.

Step 3: Secure the Wiring

Now that you have the wires connected to the 6 pin trailer plug, you will need to secure the wiring. Using electrical tape, wrap the exposed wires and secure them to the plug. Make sure you leave enough slack so that the plug can move freely. Once the wiring is secure, you can connect the plug to your trailer.

Step 4: Test the Connection

The last step is to test the connection. Using a multimeter, check the continuity of the wiring to make sure there are no shorts or other issues. Once you have verified that the wiring is correct, you can be sure that your 6 pin trailer plug is ready to use.


Wiring a 6 pin trailer plug may seem intimidating at first, but with the right tools and some basic knowledge, you can get the job done quickly and safely. With a bit of patience and attention to detail, you can be sure your trailer plug will be ready to be used in no time.
