2021-2026 Ford Bronco Auto Start Stop Eliminator | Switch Memory Harness
Description
2021-2026 Ford Bronco Auto Start Stop Eliminator
Ford's Auto-Start-Stop system is designed to shut the engine off while the vehicle is stationary under suitable operating conditions and restart it when driving resumes.
For drivers who prefer Auto Start-Stop switched off, Ford provides a physical A-OFF button. The inconvenience is that Ford specifically states that switching the system off using the button lasts for only one key cycle. When the Bronco is started again, Auto Start-Stop returns to its normal active state.
The Recontrol-X Auto Start Stop Eliminator is designed to remove that repetitive startup routine while preserving normal use of the factory control.
Designed Specifically Around the Bronco's Physical A-OFF Switch
The most important hardware difference on this product is its installation point.
This is a switch-harness memory module.
It connects directly at the rear of the Bronco's factory Auto Start-Stop switch assembly rather than installing at:
- The OBD-II diagnostic port
- A gateway module
- A fuse-box accessory circuit
- A hood-latch connector
Current established 2021-2026 Bronco eliminators use the same general approach: disconnect the original connection behind the Auto Start-Stop switch and place the memory module inline between the factory switch assembly and vehicle harness.
The connection architecture is therefore:
Vehicle Harness → Recontrol-X Memory Module → Factory Auto Start-Stop Switch
Restores Your Preferred Setting Automatically
The purpose is not to permanently remove the Bronco's Start-Stop control.
Instead, the module is designed to remember the driver's preferred state and automatically restore that preference after another ignition cycle.
This means:
- Fewer repeated A-OFF button presses
- Factory button remains useful
- No permanent software deletion
- No repeated manual reset after startup
- Original configuration can be restored later
The reason this matters is directly connected to Ford's factory logic: Bronco Auto-Start-Stop reactivates with a new ignition cycle after a temporary button-based deactivation.
Factory A-OFF Button Remains Available
After installation, the factory button remains part of the system.
If the driver wants Auto Start-Stop active during a particular drive, the original control can still be used to change the setting.
Established Bronco-specific products likewise specifically retain factory Start-Stop button functionality rather than permanently deleting the switch.
That makes “memory module” a more accurate product description than simply calling it a permanent disable device.
Full-Size Bronco and Bronco Sport Are Not the Same Application
This is probably the single most important purchasing check on the entire page.
Ford Bronco and Ford Bronco Sport are different vehicles with different electrical architectures.
A current 2021-2026 full-size Bronco product installs directly at the Auto Start-Stop switch assembly. By contrast, established 2021-2024 Bronco Sport versions use a different architecture and can connect through the vehicle's gateway module.
Therefore:
Do not order this product for a Bronco Sport simply because the model names look similar.
That distinction should stay in the product description and Q&A because it can directly reduce wrong purchases and returns.
Connector-Based and Reversible Installation
The product uses matching inline connectors rather than requiring permanent changes to individual factory wires.
Normal installation is intended to avoid:
- Factory-wire cutting
- Wire splicing
- ECU reflashing
- Permanent Start-Stop programming changes
- Occupying the OBD-II port
Comparable Bronco switch-memory modules are explicitly described as reversible: removing the module and reconnecting the original harness restores factory behavior.
2026 Bronco Remains a Relevant Auto Start-Stop Application
The supplied fitment table includes 2026 Ford Bronco, and current market-specific Bronco products likewise list 2021-2026 coverage.
Ford's official 2026 Bronco Order Guide also lists Auto Start-Stop Technology in the Bronco equipment specification, confirming the feature remains present in the current generation.
That said, the Recontrol-X table does not separately define trim, engine or transmission, so this page should still avoid unsupported statements such as:
Fits all trims
Fits all engines
Fits every manual and automatic Bronco
unless those fields are later separately verified.
Normal Auto Start-Stop Behavior Can Vary
Auto Start-Stop does not necessarily switch the engine off every time the Bronco stops.
Ford documents multiple operating conditions that determine whether the system is available and also notes that the engine can restart automatically when necessary.
So if the engine remains running during a particular stop, that does not automatically mean the memory module has failed.
Not Intended as a Repair Module
This product is designed for a normally functioning factory Auto Start-Stop system where the driver simply prefers a different default behavior.
It is not intended to repair:
Auto Start-Stop warning messages, battery problems, damaged switch assemblies, wiring faults or other vehicle malfunctions.
Ford states that if the Auto Start-Stop system detects a malfunction, the vehicle should be checked.

Reviews
S&Q
Does this fit both the Ford Bronco and Bronco Sport?
This product is designed for the listed 2021-2026 full-size Ford Bronco. Bronco Sport uses a different vehicle architecture and requires a different eliminator. Confirm your vehicle model before ordering rather than relying only on the Bronco name.
Why does Auto Start-Stop turn back on after I restart my Bronco?
That is normal factory behavior. Ford states that switching Auto Start-Stop off with the A-OFF button lasts for only one key cycle. The memory module is designed to restore your preferred setting automatically after the next startup.
Where does the module install?
It installs inline behind the factory Auto Start-Stop switch assembly. The original switch connector is disconnected and the memory harness is placed between the vehicle wiring and factory switch. This is different from an OBD-II or gateway-style eliminator.
Can I still use the factory A-OFF button after installation?
The module is designed to remember your preferred state while keeping the original factory button functional, so you can still change Auto Start-Stop when desired.
Does installation require cutting wires or programming the Bronco?
No factory-wire cutting, splicing or permanent vehicle programming is intended. The module uses an inline connector-based harness and is reversible. Removing it and reconnecting the original factory plug returns the wiring path to stock.
