These diagrams are your roadmap to safely and effectively integrating aftermarket accessories. Whether you're adding lights, winches, or auxiliary power outlets, knowing how the upfitter switches are wired will save you time, prevent damage, and ensure your modifications work as intended. This article will break down the essentials of the 2019 F350 Upfitter Switch Wiring Diagram.
Decoding the Upfitter Switch System
The upfitter switches, often found on the dashboard of Super Duty trucks like the 2019 F350, are a factory-installed feature designed to simplify the process of adding accessories. These switches are pre-wired to the vehicle's electrical system, providing dedicated circuits that can handle the power demands of various add-ons. The 2019 F350 Upfitter Switch Wiring Diagram illustrates the layout and connections of these switches, along with their associated circuits. This system is a significant advantage over trying to tap into existing vehicle wiring, which can be complex and void warranties.
The upfitter system typically includes a set of four auxiliary switches. Each switch is connected to a fused, battery-powered circuit. The diagram will show you the amperage rating for each circuit, which is critical for selecting accessories that won't overload the system. For example, you might find circuits rated at 10A, 20A, or even higher, depending on the truck's configuration. The diagram also details how these switches connect to a common power source and ground, making it clear where the accessory's power and ground wires should be terminated.
Here's a breakdown of what you'll typically find represented in the 2019 F350 Upfitter Switch Wiring Diagram:
- Switch Locations: Where the physical switches are located in the cabin.
- Circuit Identification: Each switch will be clearly labeled, often corresponding to a specific circuit number.
- Amperage Ratings: The maximum current each circuit can safely handle.
- Power Source: The battery terminal or fuse box that supplies power to the upfitter system.
- Ground Points: Designated areas where accessory ground wires can be connected.
- Relay Locations (if applicable): Some higher-amperage circuits might utilize relays, which the diagram will also show.
The importance of correctly interpreting this wiring diagram cannot be overstated . It's the foundation for a successful and safe installation. Without it, you risk blowing fuses, damaging your truck's electrical system, or creating fire hazards. Always refer to the official 2019 F350 Upfitter Switch Wiring Diagram for your specific truck model and year.
