2018-2020 Ford F-150 Auto Start Stop Eliminator Memory Harness | Plug & Play
Description
2018-2020 Ford F-150 Auto Start Stop Eliminator
Ford's Auto Start-Stop system can shut the engine off automatically under appropriate conditions when the truck comes to a stop and restart it when driving resumes. If you use the factory Auto Start-Stop button to turn the feature off, Ford specifies that the deactivation lasts for only one key cycle. After the next startup, drivers who prefer Auto Start-Stop off have to repeat the same button press.
The Recontrol-X Auto Start Stop Eliminator is designed to remove that repetitive step for compatible 2018, 2019 and 2020 Ford F-150 applications while retaining normal use of the factory control.
Automatically Restores Your Preferred Setting
The module works with the existing Auto Start-Stop switch circuit and is designed to remember and restore the preferred Auto Start-Stop state after the truck is restarted.
Key benefits include:
- Reduces repeated A-OFF button presses after each ignition cycle.
- Retains factory button functionality so the setting can still be changed manually.
- Uses the existing factory connectors instead of requiring permanent wiring changes.
- Inline plug-and-play harness design for installation behind the factory switch assembly.
- Removable installation so the original wiring connection can be restored if needed.
This memory-style operation is consistent with established F-150 Auto Start-Stop eliminators, which automatically restore the driver's preference rather than simply removing use of the original switch.
Plug-In Installation at the Factory Switch
This is a switch-harness type module, not an OBD-II module.
The eliminator connects inline at the back of the factory Auto Start-Stop switch assembly. After accessing the switch panel, disconnect the original factory connector, connect the eliminator between the vehicle harness and switch assembly, make sure both connectors are fully seated, and reinstall the trim.
The connector-based design means:
- No wire cutting
- No wire splicing
- No permanent modification to the factory harness
- Factory A-OFF switch remains available
Established F-150 harness-style eliminators use the same general installation principle: the module plugs into the back of the Auto Start-Stop switch assembly rather than permanently altering the truck's wiring.
Check the A-OFF Button Layout Before Purchase
This is one of the most important checks for this product.
Your supplied product imagery identifies the compatible switch arrangement by the position of the Auto Start-Stop button. For this version, the factory A-OFF button should be on the right side of the pictured switch group, matching the green-check FIT example.
Do not assume that every 2018-2020 F-150 uses the same connector simply because the year and model match. Different F-150 switch assemblies exist, and established F-150 harness suppliers likewise instruct customers to identify the actual switch design before selecting a harness.
Factory Control Is Still Available
Installing the eliminator does not remove normal control of the Auto Start-Stop system.
If you want Auto Start-Stop active for a particular drive, you can still use the factory A-OFF button to change the state manually. The purpose of the module is to automate the driver's preferred startup behavior, not to replace the factory switch. Comparable F-150 modules specifically retain original start-stop button functionality.
Verified Vehicle Coverage
The supplied fitment information for this product lists:
2018 Ford F-150
2019 Ford F-150
2020 Ford F-150
Trim and engine coverage are not separately specified in the supplied fitment sheet, so this page should not advertise “all trims,” “all engines,” or add individual engine sizes without separate confirmation.
The safest checkout verification is:
2018-2020 Ford F-150 + factory Auto Start-Stop system + matching A-OFF switch layout + matching connector.
Before Ordering
Confirm that:
- Your truck is a listed 2018, 2019 or 2020 Ford F-150.
- Your truck is equipped with the factory Auto Start-Stop A-OFF button.
- The A-OFF button position matches the FIT product image.
- The switch layout does not match one of the pictured NOT FIT configurations.
- The physical connector and switch panel match the product photos.
Not Intended to Repair an Existing Auto Start-Stop Fault
This product is intended for a normally functioning Auto Start-Stop system where the driver wants a more convenient default behavior.
It should not be presented as a repair for an existing Auto Start-Stop malfunction, battery problem, damaged switch, wiring fault, warning message or starting-system issue. Ford notes that Auto Start-Stop operation can depend on conditions such as battery state, climate-control demand and other vehicle operating requirements.

S&Q
Does this Auto Start Stop Eliminator fit my 2018-2020 Ford F-150?
This product is listed for 2018, 2019, and 2020 Ford F-150 vehicles, but the factory switch layout must also match. Before ordering, compare your Auto Start-Stop switch panel with the product images and confirm that the A-OFF button is in the same right-side position shown in the FIT example. Different switch layouts can use different harness connections, so model year alone is not enough to confirm compatibility. Comparable F-150 harness suppliers give the same switch-design warning.
Why do I need an eliminator if my F-150 already has an A-OFF button?
The factory button can turn Auto Start-Stop off, but Ford states that deactivating the system with the button lasts only one key cycle. That means drivers who prefer Auto Start-Stop off normally have to press the button again after restarting the truck. The eliminator is designed to automatically restore your preferred setting and reduce that repeated button press.
Can I still turn Auto Start-Stop back on after installing the module?
The module is designed to retain the factory Auto Start-Stop button functionality. If you want the system active for a particular drive, use the original A-OFF button to change the setting manually. Established F-150 eliminator harnesses use the same preference-memory approach while maintaining use of the factory button.
Where does the eliminator install, and do I need to cut any wires?
The harness installs inline behind the factory Auto Start-Stop switch assembly. Access the switch panel, disconnect the original factory plug, connect the eliminator between the vehicle harness and switch, and fully seat both connectors before reinstalling the trim. No wire cutting or splicing is required for this plug-in harness design.
Will this work with my F-150's factory remote start?
The corresponding F-150 harness design is marketed as compatible with factory remote start while retaining normal Auto Start-Stop button operation. Your supplied product reference material also identifies remote-start compatibility. As with fitment generally, confirm that the truck uses the matching factory A-OFF switch and connector configuration before ordering.
