The Power of Upfitter Switches: What They Are and How They Work
The 2020 F250 Upfitter Switch system, often referred to by its wiring diagram, is a set of pre-wired, upfittable switches located in the cabin of the truck. These switches are designed to provide power to up to six different accessories. Each switch is connected to a dedicated circuit with a specific amperage rating, ensuring that your accessories receive the correct amount of power without overloading the truck's electrical system. This thoughtful integration is what makes the 2020 F250 Upfitter Switch Wiring Diagram so valuable.
The primary function of these switches is to provide switched power, meaning that the accessory is only powered when the ignition is in the "on" or "run" position. This prevents battery drain when the truck is off. The wiring diagram details the location of the upfitter relay box, typically found under the hood, where the power connections are made. From there, the diagram illustrates how each switch is wired to its corresponding circuit. The system typically includes:
- Four 20-amp circuits
- One 30-amp circuit
- One 40-amp circuit
