What Are Ford Upfitter Switches and Why You Need the Diagram
Ford's Upfitter Switches are a brilliant factory feature designed to simplify the installation of aftermarket accessories. They offer a pre-wired solution, meaning you don't have to splice into your truck's main electrical system, which can void warranties and lead to electrical gremlins. The 2013 Ford Upfitter Switches Wiring Diagram is your roadmap to this integrated system. It details how each switch is connected, what circuits they control, and the best way to tap into them for your specific needs. Essentially, the upfitter switches are three or four pre-wired, user-accessible circuits located in the dashboard. Each switch is connected to a relay and a fuse, providing a dedicated power source for your accessories. This ensures that your added equipment doesn't overload the vehicle's existing electrical components. The diagram clarifies the following key aspects:- The function of each individual switch.
- The amperage rating of the fuses associated with each switch.
- The location of the upfitter relay box.
- The wire colors and their corresponding functions (e.g., power, ground).
| Switch | Typical Function | Amperage Rating (Example) |
|---|---|---|
| Switch 1 | Auxiliary Lights (Low Amp) | 10A |
| Switch 2 | Winch or High-Power Accessories | 30A |
| Switch 3 | Accessory Power (Constant or Ignition Switched) | 15A |
| Switch 4 (if applicable) | Customizable/Secondary Accessory | 10A |
