How do I make my Ford Upfitter switches hot all the time?

Making Ford Upfitter Switches Hot All the Time
To make the Ford Upfitter switches hot all the time, you can follow the steps outlined in the search results:
1. Procedure to Make Upfitter Switches Hot All the Time:
To make the switches hot all the time, you can cut the wire about an inch from the switch and tape off the side that comes from the roof. Then, the constant power that you’ll be adding will be the only thing going to pin 5, as opposed to tapping into it. This will ensure that the LED warning lights hooked to the upfitter switch work all the time, without the need for the truck to be in the on position or running.
2. Using 3-Blade Fuse to Make All Switches Hot at All Times:
It is suggested that by removing the plastic slider cover for the 5-amp fuse inside the upfitter fuse box and installing a 3-blade 5-amp fuse, all the switches can be made hot at all times. This method is recommended for making the remaining 20-amp switches hot at all times within factory settings.
3. Connecting to a Hot All the Time Source:
It’s mentioned that to make the upfitter switches hot all the time, you can pull pin 4 out of the connector and attach it to a hot all the time source, such as the customer access wire behind the dash. The specific fuses and pins associated with each switch are also provided for reference.
4. Jumping the Input Relay to Make Switches Always Hot:
There’s a suggestion to jump the input relay to make the 25A upfitter switches always hot, similar to how the two 40A switches can be made hot. This method is recommended for scenarios where a lower amperage is required, such as for installing an Air Command F3.
5. Configuring Upfitter Switches to Be Hot All the Time:
It’s mentioned that it is possible to configure the Super Duty Upfitter Switches, specifically Aux #5 & #6, to be hot all the time. The process involves understanding the wiring when the ignition is on and making the necessary adjustments.
6. Making Individual Upfitter Switches Hot All the Time:
There’s a discussion about making one specific upfitter switch hot all the time for a specific purpose, such as for a beacon. The process involves taking apart the switch and cutting the feed wire to splice it into a full-time power wire.
It’s important to note that while these methods have been suggested by various users, it’s recommended to exercise caution and ensure that any modifications made are in line with safety guidelines and do not pose a risk to the vehicle’s electrical system.
By following these methods, you can effectively make the Ford Upfitter switches hot all the time to suit your specific requirements.

How do Upfitter switches work?

The switches turn on the part’s corresponding relay, which is responsible for completing the circuit that powers the outfitted component. The vehicle’s ignition switch needs to be turned to the “on” position before the upfitter switches can turn on their corresponding devices.

What does a VSIM do?

The VSIM allows the upfitter turn on certain features or functions with hardwired or J1939 commands. It also has outputs signals and relay driver control circuits based on the vehicle information.

What are the aux switches for in the Ford F-250?

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.

What is the function of auxiliary switch?

Auxiliary switches provide remote electrical indication if the circuit breaker is open or closed. They are provided as two-switch combinations, with a maximum of two two-switch combinations for the NF frame and six two-switch combinations for the RF frame.

What does the Upfitter electronic module do?

The Upfitter Interface Module® 4 provides access to a broad range of vehicle data such as MPH, RPM, Park Brake, Service Brake, temperatures, transmission range, accelerator pedal, lights, ABS, MIL, etc.

What does the Upfitter interface module do?

The UPFITTER INTERFACE MODULE (UIM) is an electronic control module that provides output signals for aftermarket equipment (such as lift buckets, cranes, motors, salt spreaders, snow plows, etc.) via customer programmable logic based on switch inputs and vehicle CAN bus messages.

What is aux toggle?

It is typically used in electrical circuits to control additional functions or provide feedback on the status of the main switch. The auxiliary switch is connected to the main switch and activates or deactivates based on the position or operation of the main switch.

What is the electronic control module?

An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.

What is a Ford 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.

What is the Upfitter package on Ford Transit?

The Ford Transit can be ordered with the optional Auxiliary Upfitter Switches, which are located on the center console between the driver and passenger seat. Each Upfitter Switch can provide a 12V output to an auxiliary load, such as Air Lift Spring Kit Compressor, an exterior LED bar, etc.
