How To Install 7 Way Trailer Wiring

By | July 29, 2022





Having a trailer, but not sure how to get it up and running? Installing a 7 way trailer wiring system may sound intimidating, but it’s actually quite simple. This guide will take you through all the steps necessary to get your trailer connected to your vehicle, so you can hit the road in no time.

First, it’s important to make sure your trailer is ready for installation by making sure it’s properly connected to the towing vehicle. Next, you’ll need to identify the brake and turn signal connections, which are typically the blue wire for brakes and green for turn signals. Be sure to also locate the ground and power wires, as these will need to be attached to the vehicle battery.

Once you’ve identified the wiring and test your connections, the next step is to run the wiring from the trailer to the towing vehicle. You’ll want to use a wire or cable rated for outdoor use, which should be routed in an accessible place. Once the wiring is run, it’s time to connect it to the vehicle. This is done with a 7 way plug, which is typically found near a frame rail or bumper of the vehicle. Make sure to secure the plug securely, then connect the wiring harness to the appropriate pins on the plug.

Finally, you’ll need to test the wiring and make sure everything is working properly. To do this, you can use a digital multimeter to ensure the right kind of electricity is flowing. Once you’ve confirmed that the trailer wiring is functioning correctly, you can hit the road with confidence knowing that your trailer is safe and connected properly. With these easy steps, you’ll be able to have your 7 way trailer wiring up and running in no time.
