Upfitter switches are a key component for individuals who want to modify their 2019 F250. These switches provide additional functionality to the vehicle’s electrical system, allowing for the integration of aftermarket equipment. However, it can be a challenge to understand how to properly wire the switches into the system.
In this guide, we will provide a comprehensive overview of the 2019 F250 upfitter switch wiring diagram, including step-by-step instructions and frequently asked questions.
What are Upfitter Switches?
Upfitter switches are a set of auxiliary switches that come pre-wired from the factory. These switches are designed to provide power to additional electrical accessories, such as lighting, winches, and other aftermarket equipment. There are a total of four upfitter switches that are located in the overhead console of the 2019 F250.
The upfitter switches are rated for a maximum of 25 amps, which means that they can handle a wide range of electrical accessories. They are also designed to provide a clean and professional installation, with all wiring running directly to the fuse box and battery.
How do I Wire Upfitter Switches?
Wiring upfitter switches can be a complex process, but with the right tools and instructions, it can be completed quickly and easily. Before starting the installation, make sure to gather all necessary tools and materials.
Materials Needed:
- Upfitter switch kit (part number BC3Z-14A303-B)
- Electrical tape
- Wire cutters
- Wire strippers
- Socket set
- Flathead screwdriver
- Torx screwdriver
Once you have gathered all necessary materials, you can begin the wiring process.
Step 1: Mounting the Switches
The first step is to mount the switches in the overhead console. To do this, use a T10 torx screwdriver to remove the two screws holding the console in place. Next, carefully pull down the console and disconnect any wiring harnesses that may be attached to it.
Locate the four upfitter switch mounting holes in the console and insert the switches into the holes. Once they are in place, secure them with the supplied screws.
Step 2: Connecting the Wires
The next step is to connect the upfitter switch wires to the truck’s electrical system. To do this, locate the upfitter switch wiring harness, which is located on the passenger side of the truck, behind the glove box.
Carefully remove the wiring harness from the bracket and remove the protective covering. Next, use a wire stripper to remove approximately ¼ inch of insulation from each wire.
At this point, the wiring process will differ depending on the specific equipment being installed. For example, if you are installing off-road lights, you will need to connect the positive wire to the upfitter switch, and the negative wire to the ground stud located near the battery.
Refer to the wiring diagram provided with your installation kit to ensure that all wires are connected correctly.
Step 3: Testing the System
Once all wires have been correctly connected, it is important to test the upfitter switch system to ensure that everything is working properly. To do this, turn the key to the “on” position and activate each switch. The corresponding accessory should turn on and off as expected.
