This dedicated cancellation plug converts your factory ignition system into a memory-mode configuration, permanently deactivating the auto start-stop function until you choose to re-enable it. Designed exclusively for the Cadillac XT4 model years 2018 through 2021, the pre-routed harness intercepts the signal between your dashboard switch and the vehicle control module. Once connected, your drive cycle initiates with the system already disabled, eliminating repetitive engine cranking and safeguarding critical components during city driving and daily commutes.\u003c\/p\u003e \u003ch2\u003eBenefits \u0026amp; Practical Tips\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eEngine Protection:\u003c\/b\u003e Repeated cold starts accelerate internal wear and increase fuel consumption.

When the indicator lamp glows red, the permanent off-state is successfully locked. You can still press the switch briefly if you need the system active for a specific drive cycle.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eVehicle Compatibility:\u003c\/b\u003e Cadillac XT4 (2018–2021)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePrimary Function:\u003c\/b\u003e Disables factory automatic start-stop activation\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eInterface Type:\u003c\/b\u003e Factory-style plug-in harness connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eActivation Method:\u003c\/b\u003e Firmware-level deactivation via initial ignition sequence\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eComponent Material:\u003c\/b\u003e Automotive-grade insulated wiring with corrosion-resistant contacts\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003ePackage Includes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOne (1) suspension harness cable assembly\u003c\/li\u003e\n\u003cli\u003eOne (1) precision interior trim removal tool\u003c\/li\u003e\n\u003cli\u003eStep-by-step installation reference sheet\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eImportant Reminders\u003c\/h2\u003e\n\u003cp\u003eThis upgrade requires your original dashboard A-OFF toggle to be present; vehicles without the stock button cannot accommodate the harness.
