2020 Ford F550 Trailer Wiring Diagram

By | July 15, 2022



The 2020 Ford F550 is an extremely powerful and reliable truck that’s perfect for towing trailers and hauling loads. This truck also comes with an impressive array of features and accessories that make it an even more versatile option. One of the most important ones is the trailer wiring harness, and in order to ensure proper functioning, it needs to be wired up correctly. That’s why it’s important to know how to wire up the 2020 Ford F550 trailer wiring diagram.

It’s worth noting that this wiring diagram for the 2020 Ford F550 is very similar to previous model years, such as the 2019 and 2018 models. The main difference is that the 2020 model has been updated to include a trailer sway control module which requires additional wiring connections. This module helps keep your trailer stable at all times, even in windy conditions.

In order to properly wire up the 2020 Ford F550 trailer wiring diagram, you’ll need to first connect the seven-way trailer plug to the trailer connector on the side of the truck. Once connected, you can then connect the right-hand turn signal/stop light, left-hand turn signal/stop light, and taillight wires from the trailer harness to the corresponding locations on the truck.

Next, you’ll want to connect the center console power wiring harness to the vehicle’s fuse box. This will ensure that the trailer remains powered up at all times when the truck is running. Finally, you’ll want to connect the trailer brake control module wire to the vehicle’s electronic brake module. By doing this, you can control the trailer’s brakes from inside the cab.

All in all, wiring up the 2020 Ford F550 trailer wiring diagram is relatively straightforward if you’re familiar with automotive wiring. Just make sure to double check that all the connections are made correctly, and that none of the wires are pinched or damaged. If done correctly, the trailer should operate correctly and safely with no issues.
