What Are Ford Upfitter Switches and How They Work
Ford Upfitter Switches are a fantastic feature designed for commercial and vocational trucks, including the 2017 Ford Super Duty line. They provide a pre-wired and easily accessible power source for aftermarket accessories such as light bars, plows, strobes, auxiliary fuel pumps, and more. Essentially, these switches connect directly to the vehicle's electrical system, allowing you to control your added equipment directly from the driver's cabin. This eliminates the need for complex, custom wiring for each accessory, saving time and reducing the risk of electrical issues. The importance of using the correct 2017 Ford Upfitter Switches Wiring Diagram cannot be overstated for a clean and reliable installation.
The Upfitter Switches typically consist of a set of up to six auxiliary upfitter switches located in the dashboard or overhead console. Each switch is connected to a dedicated circuit that can handle a specific amperage load. These circuits are powered by the vehicle's battery and are often fused for protection. The wiring diagram details how these switches interface with the main power supply, the ground, and the output terminals where you will connect your accessories. Understanding the flow of power through these circuits is key. Here's a breakdown of common components:
- Upfitter Switches: The physical buttons that control power to your accessories.
- Relays: Often used to handle higher amperage loads, allowing the small switch to control a more powerful circuit.
- Fuses: Protect the electrical system and accessories from damage due to overcurrent.
- Wiring Harness: The set of wires connecting the switches, relays, and output terminals.
When you flip an Upfitter switch, it completes a circuit, sending power to the connected accessory. The 2017 Ford Upfitter Switches Wiring Diagram will illustrate the different types of circuits available. Some may be configured as positive-switched, meaning power is supplied when the switch is on, while others might be negative-switched, offering different control capabilities. Some diagrams will also show specific output terminals that are designed to power equipment when the ignition is on, or when the vehicle's high beams are activated. A typical setup you might find on a 2017 Ford Super Duty includes:
| Switch Designation | Typical Use | Amperage Rating (Example) |
|---|---|---|
| Switch 1 | Light Bars, Plow Lights | 30 Amps |
| Switch 2 | Emergency Strobes, Work Lights | 30 Amps |
| Switch 3 | Auxiliary Fans, Inverters | 20 Amps |
| Switch 4 | Communication Equipment, Small Accessories | 10 Amps |
