2025-2026 Buick Enclave Auto Start Stop Eliminator | Plug & Play
Description
2025-2026 Buick Enclave Auto Start Stop Eliminator
Buick's Stop/Start Technology can automatically shut the engine off when the Enclave is stopped and restart it when the driver releases the brake pedal. Buick also states that Stop/Start is enabled each time the vehicle is started on vehicles equipped with the deactivation control.
For Enclave owners who prefer the engine to remain running at routine stops, the Recontrol-X Auto Start Stop Eliminator provides a dedicated inline K9 BCM solution without cutting the original harness.
Designed Around the Actual Auto Stop Pain Point
Auto Stop disabled by default: Reduce the repeated task of manually dealing with Auto Stop after each startup.
No permanent factory harness modification: The module installs inline with existing BCM connections.
Vehicle-specific connection: This is a dedicated Enclave application rather than a universal diagnostic-port accessory.
The 2025+ Enclave already has a dedicated Auto Stop Eliminator market, and real buyers specifically cite eliminating unwanted engine shutdown and straightforward installation as key reasons for purchasing.
5.98-Inch Plug-In Module
The supplied harness measures approximately:
5.98 inches overall
The compact control module sits between two matching connectors and is designed to fit inline in the factory harness path.
K9 BCM X3 Installation
Access the K9 Body Control Module on the driver side of the Enclave.
Identify BCM X3.
Disconnect the original vehicle harness from X3.
Connect the Recontrol-X module between the K9 BCM and factory harness.
Fully seat and lock both connections.
No factory wire cutting
No splicing
No permanent harness alteration
Identify the Correct Module Before Connecting Anything
The installation guide distinguishes two nearby connectors:
K9 BCM — 8-socket connector — correct
LCM — 5-socket connector — incorrect
Do not assume the closest blue-style connector is automatically the right one.
Locate the K9 BCM first, then verify the connector has 8 sockets.
This is one of the highest-value pieces of installation information on the page because using the wrong nearby connector is an avoidable mistake.
Vehicle Fitment
Designed for:
2025 Buick Enclave
2026 Buick Enclave
Trim and engine combinations are not separately specified.
Even though some external competitor products now list 2027, the Recontrol-X PDP should not claim that year until your own fitment data verifies it.
Before You Order
Confirm 2025 or 2026 Buick Enclave.
Confirm the vehicle has factory Stop/Start Technology.
Check the K9 BCM installation area.
Verify the 8-socket X3 connector rather than the nearby 5-socket LCM connector.
Not Intended as a Fault Repair
This product manages normal Auto Stop behavior.
It does not repair:
Electrical warning lights
Charging-system faults
Battery issues
Damaged BCM connections
Abnormal engine starting or stalling
Buick notes that battery charge, temperature, HVAC demand, transmission state and other operating conditions may cause Auto Stop not to occur or the engine to restart automatically.

Reviews
S&Q
Does this Auto Start Stop Eliminator fit the 2025 and 2026 Buick Enclave?
It is designed for 2025 and 2026 Buick Enclave applications equipped with factory Stop/Start Technology. This listing does not claim 2027 fitment, so order based on the years shown here rather than a different seller's wider compatibility range.
What problem does the module solve?
It is designed for Enclave drivers who prefer Auto Stop disabled and do not want the engine automatically shutting down during normal stops. Buick normally enables Stop/Start again when the vehicle is restarted.
Where does it install?
Installation is at the K9 Body Control Module on the driver side of the vehicle. The harness installs inline at BCM connector X3 between the module and factory vehicle wiring.
Which connector should I use?
Use the 8-socket connector on the K9 BCM. Do not connect the harness to the nearby 5-socket LCM connector. Confirm the socket count and module location against the installation image before plugging anything in.
Do I need to cut the factory wiring?
No. The harness uses an inline connector-based installation. Disconnect the original BCM X3 plug, install the eliminator between the BCM and factory harness, and fully seat the connectors. The original wiring does not need to be cut or spliced.
