What Are Upfitter Switches and How Do They Work?
The upfitter switches on your 2017 Ford F350 are essentially pre-wired relays and circuits designed to make it easier to add electrical accessories. Ford includes these from the factory, anticipating the need for truck owners to power various equipment. They are typically located in a convenient spot within the cabin, often near the steering column or on the dashboard. The beauty of these switches is that they bypass the need for complex, custom wiring harnesses for many common additions.
Each upfitter switch is connected to a dedicated circuit that can handle a specific amount of amperage. This means you can connect items like:
- Emergency lighting
- Work lights
- Snow plows
- Inverters
- Other power tools
The 2017 Ford F350 Upfitter Switch Wiring Diagram outlines the power source, the relay, the fuse, and the output terminal for each switch. This allows for a clean and organized installation, preventing potential electrical issues. The importance of using the factory upfitter circuits cannot be overstated for maintaining warranty and ensuring safe operation of your truck.
Here's a simplified breakdown of how the circuits generally function:
- Accessory Connection: You connect your accessory's positive wire to the designated upfitter switch output terminal.
- Grounding: You connect your accessory's negative wire to a suitable ground point on the truck's chassis.
- Switch Activation: When you flip the corresponding upfitter switch inside the cab, it activates the relay.
- Power Flow: The activated relay then allows power to flow from the truck's battery, through the fuse, and to your connected accessory.
The diagram will detail the amperage rating for each switch, which is critical information for selecting the right accessories. For example, you might find:
| Switch Label | Max Amperage |
|---|---|
| Switch 1 | 30 Amps |
| Switch 2 | 30 Amps |
| Switch 3 | 10 Amps |
