RAM 1500 Auto Start Stop Eliminator | Gateway Memory Harness
Description
RAM 1500 Auto Start Stop Eliminator – Gateway Memory Harness
The RAM 1500 Stop/Start system is designed to shut the engine off automatically during qualifying stops and restart it as the driver prepares to move again.
RAM's official documentation describes the feature as “Stop/Start System — If Equipped.” On equipped trucks, the system is enabled after a normal engine start. The 2020 RAM 1500 owner's manual further states that when Stop/Start is manually switched off using the factory button, it resets to ON after the ignition is cycled.
For drivers who regularly prefer the system off, the Recontrol-X memory harness is designed to eliminate that repeated startup routine.
Gateway-Module Architecture
This is the main product-specific difference.
The module does not simply connect to the rear of the A-OFF dashboard button.
Instead, it uses a larger inline harness designed around the RAM 1500's gateway-module electrical connection.
The operating architecture is:
Factory Vehicle Harness → Memory Module → Gateway Module
Established 2019–2024 RAM 1500 eliminators use this same general installation concept, with the module installed inline at the gateway connection below the steering-wheel area.
This makes the product structurally different from:
- Small switch-button pigtails
- OBD-II devices
- Fuse-tap modules
- Subaru multi-pin fused harnesses
- Hood-latch style eliminators
That distinction should remain visible throughout this PDP.
Remembers the Driver's Stop/Start Preference
The purpose is not simply to disconnect the factory system.
Instead, the module is designed to restore the preferred Stop/Start state after another vehicle startup.
That means the customer gets the convenience of fewer repeated A-OFF button presses while retaining access to the factory control.
The RAM owner's manual confirms that the Stop/Start OFF switch is located near the gear-selector area and that pressing it disables the system until the system is subsequently reset.
Factory A-OFF Control Remains Available
A memory module and a permanent system deletion are not the same thing.
If the driver wants Stop/Start active for a particular drive, the original A-OFF control remains relevant. Comparable RAM 1500 gateway modules specifically retain normal factory Stop/Start button operation.
This makes the product more accurately described as a:
Stop/Start Preference Memory Module
rather than a permanent software removal of the feature.
Connector-Based, Reversible Installation
The harness is intended to connect inline using the existing vehicle connector architecture.
Normal installation therefore does not require:
- Cutting factory wires
- Splicing individual conductors
- Reflashing the ECU
- Leaving a device permanently connected to the OBD-II diagnostic port
Comparable RAM gateway eliminators are installed between the original harness and gateway connection and can be removed to restore the factory wiring path.
Only Trucks With Factory Stop/Start Need This Product
RAM describes Stop/Start as an “If Equipped” feature.
On current eTorque-equipped RAM 1500 applications, RAM explains that Stop/Start uses the motor-generator and hybrid battery system as part of engine shutdown and restart operation.
Therefore, customers should first confirm that their truck actually has the factory:
A-OFF / Stop-Start OFF control
shown in the product images.
If the truck does not have factory Stop/Start, there is no Stop/Start preference for this module to manage.
Important Fitment Gap: 2021
The supplied Recontrol-X fitment table lists:
2019 RAM 1500
2020 RAM 1500
2022 RAM 1500
2023 RAM 1500
2024 RAM 1500
It does not list 2021.
Some competing 2019–2024 RAM gateway modules do advertise 2021 compatibility, but at least one established supplier also publishes a special 2021 compatibility check involving the factory OFF indicator light.
That makes it especially important not to silently add 2021 to this SKU.
If 2021 is eventually intended to be covered, the source fitment table should be verified and corrected first.
2025 Is a Separate Application
Do not extend this product into 2025 simply because it fits earlier fifth-generation RAM 1500 trucks.
Current established suppliers specifically identify 2025 RAM 1500 as requiring a different product/module.
That provides another useful SEO and customer-service boundary:
this page is not for 2025+ RAM 1500 applications.
Normal Stop/Start Behavior Can Vary
Even when Stop/Start is enabled, RAM states that the engine will not automatically stop under every condition.
Examples include:
- Battery charging requirements
- High heating or cooling demand
- Full defrost
- Engine-temperature conditions
- 4WD LOW
- Tow/Haul mode
- Excessive electrical load
So an engine continuing to run at a stop does not necessarily indicate a problem with the module or truck.
Not Intended as a Repair Module
This product is intended for a normally functioning factory Stop/Start system.
It is not a repair for:
“Service Stop/Start System” messages, battery issues, electrical faults, damaged switches or other vehicle malfunctions.
RAM's manual states that a malfunction can trigger a SERVICE STOP/START SYSTEM message and requires diagnosis.

Reviews
S&Q
Which RAM 1500 model years are listed for this product?
This version is listed for 2019, 2020, 2022, 2023 and 2024 RAM 1500. The supplied fitment data does not include 2021, so 2021 compatibility should not be assumed from other products on the market. Confirm your model year and the factory connector before ordering.
Where does the Auto Start Stop Eliminator install?
This is a gateway-style inline memory harness. It connects into the factory gateway circuit below the steering-wheel area rather than directly behind the dashboard A-OFF button or through the OBD-II port. Comparable RAM 1500 modules for this generation use the same general gateway connection.
Will the factory Stop/Start OFF button still work?
Yes. The module is intended to remember the driver's preferred setting rather than permanently remove factory control. You can still use the original A-OFF switch when you want to change the Stop/Start state.
Does this work on a RAM 1500 that does not have the factory A-OFF button?
It should not be ordered for a truck that does not have the factory Stop/Start system. RAM identifies Stop/Start as an “If Equipped” feature. Confirm that your truck has the factory Stop/Start OFF control and that the connector matches the product images before purchasing.
Can I use this on a 2025 RAM 1500?
2025 is not included in this product's fitment. Established RAM-specific suppliers identify the 2025 truck as requiring a different Start/Stop module, so do not extend this harness to 2025 simply because the vehicle is also a RAM 1500.
