2021-2026 GMC Yukon XL Auto Start Stop Eliminator | Plug & Play
Description
2021-2026 GMC Yukon XL Auto Start Stop Eliminator
The GMC Yukon XL uses an automatic Stop/Start system that can shut the engine off at a complete stop and restart it as driving resumes. Current GMC specifications continue to describe an Automatic Stop/Start disable button that applies with each engine cycle, which is why owners who consistently prefer Auto Stop off may need to repeat the setting after restarting the vehicle.
The Recontrol-X Auto Start Stop Eliminator is designed to keep unwanted Auto Stop behavior OFF by default and eliminate that repetitive part of the driving routine.
Designed for Drivers Who Prefer Auto Stop Off
Less repeated button pressing: The product is intended to maintain the preferred OFF behavior rather than requiring the same manual action after every restart.
No permanent wire modification: The harness connects through the existing BCM connector.
Removable whenever needed: Return the vehicle to its original electrical connection by removing the module and reconnecting the factory plug.
Plug-In Installation at the BCM
Access the lower driver-side instrument panel and remove the lower trim.
Locate the K9 Body Control Module.
Identify the correct dark blue factory connector.
Disconnect the factory connector and plug the Recontrol-X harness inline.
Ensure all connector locks are fully engaged before replacing the trim panel.
Critical Installation Detail
The BCM contains multiple color-coded plugs.
Connect only to the dark blue plug shown in the installation image. Do not use the light blue plug beside it.
This is an important part of correct installation because the two blue connectors can be easily confused when viewed from underneath the dashboard.
No cutting of factory wires
No splicing
No permanent electrical modification
No ECU or OBD-II programming process required by the installation procedure

Current specialist products also treat 2021–2026 Yukon / Yukon XL as an established Auto Stop Eliminator application, and the customer feedback is heavily centered on simple installation and eliminating repeated Start/Stop button operation.
Trim and engine combinations are not separately specified on this listing. If your BCM wiring differs from the installation image, verify compatibility before ordering rather than forcing the connector.

Reviews
S&Q
Is this Auto Start Stop Eliminator compatible with my GMC Yukon XL?
It is designed for 2021 through 2026 GMC Yukon XL applications. Check the BCM connector shown in the installation guide before ordering if the vehicle has undergone previous wiring or electrical modifications.
Will this stop me from having to turn Auto Stop off after every restart?
That is the intended purpose. The module is designed to keep the unwanted Auto Stop setting off by default so drivers who prefer it disabled do not have to repeat the same button press after every engine cycle.
Where does the Yukon XL Auto Stop Eliminator plug in?
It installs at the K9 Body Control Module behind the lower driver-side instrument panel. The correct installation point is the dark blue connector, not the light blue connector beside it.
Do I need to cut wires or connect an OBD-II scanner?
No. The product installs inline with the existing BCM connector, so the factory wiring does not need to be cut or spliced. The installation procedure does not require an OBD-II scanner or ECU reprogramming.
Can I remove it later?
Yes. The inline harness is removable. Disconnect the eliminator and reconnect the original factory BCM connector to restore the original connection.
