Ford Upfitter Switches Amps

Upfitter switches are an easy way to add additional accessories to your vehicle. By adding a switch, you can control an accessory without having to run wires through the firewall or dash. Switches are available in 1-, 2-, and 4-pole configurations with amperage ratings of 20, 30, and 40 amps.

What are Ford Upfitter Switches Used for

If you’ve ever wondered what those little switches are on the side of your Ford truck’s dash, they’re called upfitter switches. They’re commonly used to control aftermarket accessories that have been installed by an upfitter, like auxiliary lights, a winch, or a compressor. Upfitter switches are typically installed by the manufacturer and wired to run power directly from the battery to the accessory.

This eliminates the need for splicing into factory wiring, which can void your warranty. To use an upfitter switch, simply flip it to the “on” position when you want power to flow to your accessory. When you’re done using it, flip it back to the “off” position so you don’t accidentally drain your battery.

If your truck didn’t come with upfitter switches and you’d like to add them, there are a few different ways to do it. You can buy a kit that includes everything you need or wire them yourself using relays. Either way, adding upfitter switches is a relatively simple process that anyone with basic automotive knowledge can do.

F250 Upfitter Switches

If you’ve ever wondered what those little switches to the left of your steering wheel are for, wonder no more! Those are called upfitter switches, and they’re there to provide power to aftermarket accessories that you might want to add on to your truck. There are four main types of upfitter switches: relay control, constant power, ignition-powered, and battery-powered.

Relay control switches activate a relay when turned on, which then provides power to the accessory. Constant power switches provide a constant flow of electricity to the accessory, even when the truck is turned off. Ignition-powered switches only provide power when the key is in the ON or ACC position.

Battery-powered switches provide power even when the key is in the OFF position – but be aware that this will drain your battery if left on for too long! Now that you know what upfitter switches are and what they do, you can start thinking about which accessories you might want to add on to your truck. Popular choices include auxiliary lights, electric winches, air compressors, and more.

Whatever you choose, just be sure to consult with a professional before making any modifications – and have fun customizing your ride!
