How To Fit A 7 Pin Trailer Plug

By | August 4, 2022



Fitting a 7 pin trailer plug may seem daunting for first-time DIY-ers, but with some patience and guidance it can be done with just a few simple steps.

The first thing you need to do is make sure you have all the tools required. You’ll need a flat head screwdriver, a wire cutter/stripper, some electrical tape, and a 7 pin trailer plug. Make sure that everything you’ll need is accessible. Take note that if you do decide to use electrical tape it is highly recommended to use electrical heat shrink instead, as it provides added protection from moisture and corrosion.

The next step is to strip back the wiring of the trailer plug. This is done by cutting off small sections of the plastic sheathing of the wires. It is very important that you are precise when doing this, as you don’t want to damage any of the wires or short out the trailer plug. Once you have stripped the wires back, you will need to connect them to the appropriate pins on the trailer plug. You will want to ensure that you connect the positive (red) wires to the positive pin, the negative (black) wires to the negative pin, and so on. A good tip is to twist the wires together before connecting them to the pins on the plug. This will ensure a secure connection and help protect the wires from any damage.

Finally, once all the wires are connected, it’s time for the final step. Use the electrical tape or heat shrink to firmly secure the connections and protect them from weather elements. This is an important step to ensure that your connection remains strong and your trailer plug works correctly.

Once you’ve completed all of these steps, you should have a functioning 7 pin trailer plug! If the whole process was done correctly, there should be no problems in the future. So, with a bit of patience, guidance, and the right tools, fitting a 7 pin trailer plug is just a few steps away.
