If you own a 2016 F250 and want to add some custom electrical accessories to your vehicle, you may be wondering how to wire up the upfitter switches that come installed from the factory. In this article, we will provide you with a comprehensive guide to understanding the wiring diagram for the upfitter switches so you can install your custom accessories with ease.
What are Upfitter Switches?
Upfitter switches are auxiliary switches that are pre-installed by Ford on certain trucks to allow owners to easily add custom electrical accessories to their vehicles. These switches are installed in the overhead console and are designed to handle high-current loads, making them ideal for powering up custom accessories such as extra lights, winches, or air compressors.
The 2016 F250 comes with up to six upfitter switches, depending on your truck’s configuration. These switches are numbered 1 through 6 and are located in a bank on the overhead console, just above the rearview mirror. The upfitter switches are labeled with their corresponding function and can handle a maximum current of 30 amps.
Understanding the Wiring Diagram
The wiring diagram for the upfitter switches is a bit complex and can be intimidating for beginners. However, with a little bit of patience and attention to detail, anyone can figure out how to wire up the switches and install their custom accessories. Here’s what you need to know:
The upfitter switches are wired to relays that are located in the engine compartment of your truck. These relays act as electrical switches that can handle high-current loads and protect your truck’s electrical system from damage.
Each upfitter switch is wired to a single relay, and each relay is wired to a specific electrical component or circuit. For example, upfitter switch #1 is wired to relay #1, which then powers the high-current circuit for your custom accessory.
The wiring diagram for the upfitter switches can be found in your truck’s owner’s manual or online. Make sure you refer to the correct diagram for your specific truck configuration.
Wiring the Upfitter Switches
Now that you understand the wiring diagram, it’s time to wire up your upfitter switches. Here’s a step-by-step guide:
- Identify the electrical component or circuit that you want to power with your upfitter switch.
- Locate the appropriate relay in your truck’s engine compartment.
- Connect one end of a 12-gauge wire to the appropriate relay terminal (refer to the wiring diagram).
- Run the wire through the firewall and into the interior of your truck.
- Connect the other end of the wire to the corresponding upfitter switch (refer to the labeling on the switch).
- Repeat this process for each upfitter switch and circuit that you want to power.
