The Ford Upfitter switches are optional instrument panel mount switches that control passenger side mounted relays. These relays power four blunt cut wires that are taped beneath the instrument panel near the steering column.
Auxiliary switches are used to indicate the position of the main contacts- open or closed, as well as indicator lights, relays, and other accessories. The switches feature self-cleaning contacts.
What is AUX switch F250?
The auxiliary switchboard on the overhead console makes aftermarket customization easier with six prewired switches connected to the power distribution box. Each circuit is individually fused for connection of electrical accessories. The switches are labeled AUX 1 through AUX 6.
Where are the wires for the Upfitter switches?
On a 2021 F250, the upfitter wires come straight from the upfitter fuse box, in the engine compartment, passenger side. It’s easy to push the two clips and pull the small fuse box up, and you can remove the black tape, and all of the upfitter switches are there and labeled.

Where are the Upfitter wires on a 2020 f250?
What is an Upfitter relay?
The Ford Upfitter Switches are optional instrument panel mount switches (Option Code 66S) that control passenger side mounted relays. These relays power four blunt cut wires that are taped on a harness near the relay pack that can be found beneath the instrument panel and to the left of the steering column.
Why use a relay instead of a switch?
Relays can reduce the need for high-amperage wiring and switches, which are expensive and take up space. Therefore, switching to relays in your electronic systems can reduce the size or weight of a casing, for instance, or allow manufacturers to fit more functionality into a space of the same size.
How does a switching relay work?
A relay is an electrically operated switch. They commonly use an electromagnet (coil) to operate their internal mechanical switching mechanism (contacts). When a relay contact is open, this will switch power ON for a circuit when the coil is activated.
What can be used as a switching relay?
Bipolar transistors (BJT’s) make very good and cheap relay switching circuits, but BJT’s are current operated devices as they convert a small Base current into a larger load current to energise the relay coil.
What are 5 pin relays used for?
Do I need a relay for LED lights?
LED lights do not need relays to operate. Yet, doing so is not recommended. It is best to use a relay when you are unsure about switches, fuses, and wiring is of the proper size for the amperage.
Using a relay as a heavy-duty, remote-control device ensures delivery of full power to high-load electrical components: Your headlights will burn brighter, your electric fan will run faster, and fuel pumps will operate at their peak efficiency.
How many amps before you need a relay?
You will often see circuits carrying less than 20 amps switched directly, while circuits of 30-40 amps can sometimes be directly switched but will often be controlled by relays. Anything above 40 amps is pretty much always on a relay.
Why do you need a relay for a horn?
The horn relay is responsible for controlling the power supply to the horn circuit of your vehicle. Without it, the horn may not function because there will be no power supply. The horn relay helps to switch a large current to your car’s horn from the button of the low-current horn in your car’s steering wheel.
How many volts does it take to trigger a relay?
The nominal voltage of a 12V relay is 12V, so 80% of this is 12 x 0.8 = 9.6V. So in theory, this relay should activate at 9.6V.
What is pin 85 on a relay?
85 and 86 are the coil pins while 30, 87, and 87a are the switch pins. 87 and 87a are the two contacts to which 30 will connect. If the coil is not activated, 30 will always be connected to 87a.
Once the relay has pulled in, most “24V” relays will hold in quite satisfactorily on 12V or even less. So there’s actually no need for a continuous 24V supply – all you really need is that first short pulse.
Are all 5 pin relays the same?
The problem is, not all relays are the same. Many relays, if installed for the wrong application, could and will cause a short (Internal Relay Circuit) and most likely cause functionality issues or even damage to the vehicle computer systems.
What happens if you use the wrong relay?
The wrong relay can cause a short or a power surge that can damage your vehicle’s electrical system.
