2020-2025 Kia Soul Auto Start Stop Eliminator | ISG Plug & Play
Description
2020-2025 Kia Soul Auto Start Stop Eliminator
The Kia Soul uses an Idle, Stop and Go (ISG) System that can automatically shut the engine off while the vehicle is stopped and restart it when driving resumes. Kia provides an ISG OFF button for drivers who want the system disabled, but the factory OFF selection is temporary.
Kia specifically states that the ISG System turns back ON when the engine is turned off and started again.
The Recontrol-X Auto Start Stop Eliminator is designed for Kia Soul drivers who prefer ISG OFF and do not want to repeat the same button press every time they start the vehicle.
Automatically Restore Your ISG OFF Preference
No repeated ISG OFF routine: The module is designed to place unwanted Idle Stop behavior in the OFF state after startup, so the driver does not have to remember the same switch press on every trip.
Factory button remains functional: If you want ISG operating again during a particular drive, the original button remains available for manual control.
No permanent software change: The module works through the factory ISG switch circuit rather than requiring an engine tune or permanent software alteration.
This is also how established Soul-specific switch-interface products describe their operation: they plug into the back of the Auto Stop/Start switch assembly, automatically restore the driver's preference after an ignition cycle, and retain the factory button functionality.
Driver-Side Dash Plug-In Installation
This Kia Soul application installs behind the factory ISG OFF / Auto Start-Stop switch on the driver's side of the dashboard.
The supplied installation guide shows the following procedure:
1. Carefully remove the driver-side dash trim panel using a non-marring plastic trim tool.
2. Reach behind the dashboard and locate the electrical connector attached to the factory Auto Start-Stop switch assembly.
3. Disconnect the original factory connector.
4. Insert the Recontrol-X eliminator inline between the factory switch and the original vehicle harness.
5. Make sure both connectors are properly seated before reinstalling the trim panel.
6. Start the vehicle and verify normal switch operation.
Factory-Style Inline Connection
The product uses matching multi-pin connectors on both ends of the harness.
That means the installation is designed around the existing factory electrical path rather than requiring the original wiring to be cut.
No factory wire cutting
No wire splicing
No permanent modification of the switch connector
No engine-bay sensor needs to be disconnected
No OBD-II dongle needs to remain plugged in
The supplied product image also includes a plastic trim-removal tool, which is appropriate for accessing the driver-side dash panel without intentionally using metal tools against the interior trim.
The Factory ISG OFF Button Still Matters
A common customer concern is:
If I install this, can I ever turn ISG back on?
Yes—the purpose of this type of switch-interface eliminator is to change the startup preference, not remove the factory switch.
Once installed, the module is designed to restore the preferred OFF state automatically.
If you want the factory Idle, Stop and Go system active during a particular drive, use the original ISG button to change the setting.
Current dedicated 2020–2025 Soul products specifically advertise retained Start/Stop button functionality, and this is one of the key reasons this approach is more useful than a crude workaround.

Trim and engine combinations are not separately specified for this listing.
Current specialist-market products independently identify 2020–2025 Kia Soul as a dedicated Auto Stop / ISG eliminator application, so the year/model combination itself has clear commercial search intent.
Check Your ISG Equipment Before Ordering
Model year alone should not be the only visual check.
Confirm your Kia Soul actually has the factory ISG OFF / A-OFF button shown in the images.
On the Kia Soul, the factory ISG OFF button is located on the driver-side control panel to the left of the steering wheel. This location is also documented in Kia-focused ISG guidance.
If your vehicle does not have this factory switch, or the connector arrangement differs from the product and installation photos, verify compatibility before ordering.
Before Checkout
Confirm your vehicle is a 2020-2025 Kia Soul.
Confirm the factory ISG OFF / A-OFF switch is present to the left of the steering wheel.
Compare the driver-side switch panel and connector with the installation images.
If aftermarket equipment has modified this wiring area, inspect the connection before ordering.
Do not purchase an eliminator simply because ISG has stopped functioning unexpectedly.
This Product Is Not an ISG Repair Device
The eliminator is intended for a normally functioning ISG system that the driver simply prefers to keep OFF.
It does not diagnose or repair:
A blinking ISG warning indicator
Battery or charging-system problems
Existing wiring or switch faults
Abnormal starting or stalling
ISG conditions that are not being met
Kia itself notes that when the ISG warning lamp is amber, the system may be functional but its enabling criteria have not been met; Kia also instructs owners to seek service if the Auto Stop indicator continuously blinks amber and the ISG button LED remains on.
This distinction helps prevent customers from buying an eliminator for a vehicle that actually needs diagnosis.

Reviews
S&Q
Does this Auto Start Stop Eliminator fit my 2020-2025 Kia Soul?
It is designed for 2020, 2021, 2022, 2023, 2024, and 2025 Kia Soul vehicles equipped with the factory Idle, Stop and Go (ISG) system. Before ordering, confirm your Soul has the factory ISG OFF / A-OFF button on the driver-side control panel and compare the switch connector with the installation images.
Will I still need to press the ISG OFF button every time I start my Kia Soul?
No. The eliminator is designed to automatically restore the ISG OFF preference when the vehicle starts, so you do not have to repeat the same button press on every drive. Kia states that the factory ISG system normally turns back ON after the engine is switched off and restarted.
Can I turn Idle Stop and Go back on after installing the eliminator?
Yes. The factory ISG OFF button remains functional. If you want the Idle, Stop and Go system active for a particular drive, use the original button to change the setting. The eliminator changes the startup preference rather than permanently taking away your control of ISG.
Where does the module install, and do I need to cut any wires?
It installs behind the factory ISG OFF / Auto Start-Stop switch on the driver side of the dashboard, to the left of the steering wheel. Remove the side dash trim with a plastic trim tool, unplug the factory switch connector, and connect the eliminator inline between the button and original vehicle harness. No cutting or splicing of the factory wiring is required.
My Kia Soul already shows an ISG warning or Auto Stop no longer works. Will this module fix it?
No. This product is intended for a normally functioning ISG system that you simply prefer to keep off. If the ISG warning lamp is on, the Auto Stop indicator is blinking, or the system has stopped operating because its enabling conditions are not being met, diagnose that condition separately. Kia specifically provides warning guidance for these situations.
