2019 Ford F350 Trailer Wiring Diagram

By | December 27, 2022



If you’ve ever owned a Ford F350 pickup truck, you know how important it is to have the right wiring diagram in hand. After all, without a properly drawn wiring diagram, you could end up facing costly repairs if something goes wrong with your trailer wiring. Fortunately, you don’t have to stress out when it comes to understanding the wiring diagram for your 2019 F350 pickup truck. We’re here to walk you through each step so you can get your trailer and cargo securely connected in no time.

Before we get into the wiring diagram itself, let’s take a quick look at the components you’ll need for the installation. You’ll need a trailer hitch, 4-way trailer wiring harness, and trailer brake controller. Additionally, it’s important to make sure your Ford F350 has the towing package before you attempt any wiring installation.

Now that you have the necessary parts, let’s take a look at the wiring diagram. Your first step will be to locate the tail light assembly on the rear of your pickup. Once you’ve located this, you can then connect the 4-way wiring harness connector to the tail light assembly. From here, the wiring will run along the frame of the truck until it reaches the battery.

At this point, you’ll need to attach the wiring to the positive terminal of the battery. This is critical because it supplies power to the trailer brakes, lights, and turn signals. From here, you’ll want to attach the trailer brake controller and connect it to the trailer hitch as well. This is also an important step because it helps control the braking power to the trailer when you apply the brakes while driving.

Once you have everything connected, you should double-check your connections to make sure everything is secure and there are no loose wires. Once you’ve done this, you can enjoy the convenience of knowing your trailer is safe and secure when connected to your 2019 Ford F350 pickup truck. So take your time, follow the wiring diagram, and enjoy the peace of mind that comes from having a properly installed trailer wiring setup.
