Understanding the 2019 F350 Upfitter Switch Wiring Diagram is essential for anyone looking to customize their Super Duty truck. These factory-installed switches provide a convenient and integrated way to power auxiliary equipment, transforming your F350 into a versatile workhorse or specialized vehicle.
What are Upfitter Switches and How Do They Work?
The 2019 F350 Upfitter Switch Wiring Diagram outlines a system of up to six pre-wired auxiliary switches located in the overhead console. These switches are designed to simplify the installation of aftermarket accessories such as emergency lights, winches, snowplows, toolboxes with lights, or even custom sound systems. Instead of running wires directly from the battery and dealing with complex fuse box connections, the upfitter switches offer a clean and factory-approved solution. Each switch is linked to a dedicated circuit with a corresponding relay and fuse, providing power when the switch is activated.
The beauty of the upfitter system lies in its flexibility. The diagram shows that each switch can be configured to operate in different modes, offering both constant power and switched power. This means you can choose whether an accessory runs all the time (like a security light) or only when the ignition is on (like a work light that shouldn't drain the battery when parked). The wiring itself is typically routed to a central upfitter connector under the dashboard or in the engine bay, making it accessible for connecting your accessories. The importance of consulting the specific 2019 F350 Upfitter Switch Wiring Diagram cannot be overstated , as it dictates the correct wire colors and terminal assignments for each circuit.
Here's a breakdown of what you'll typically find associated with the upfitter switches:
- Switched Circuits: Usually a higher amperage circuit for demanding accessories.
- Unswitched Circuits: For accessories that need constant power.
- Accessory Power: Often a lower amperage circuit for less power-hungry devices.
Additionally, the system is designed with safety and ease of use in mind. The diagram will illustrate:
- The wire color for each upfitter switch output.
- The location of the corresponding relay and fuse for each circuit.
- The upfitter connector pinout, which tells you where to connect your accessory wiring.
