Automatic Stop Start Off Switch for Cadillac CT6 2016 2017 2018

Ditch the automatic engine restart nuisance with a dedicated bypass harness engineered specifically for Cadillac CT6 models from 2016 through 2018. This plug-and-play switch module permanently disables the factory start-stop function, eliminating the need to pause your commute just to silence the idle cycle. By keeping the engine running continuously after ignition, you prevent excessive starter motor wear, reduce battery drain, and maintain smoother cabin comfort during low-speed traffic and temporary stops.

The installation requires simply removing your dashboard panel and inserting the adapter between the existing factory connector and the button socket. Once wired, starting the vehicle with the brake pedal engaged while leaving the switch untouched for three to six seconds locks the default setting. The button illumination shifts to red, confirming that engine restart is now deactivated until you choose to reactivate it manually.

Benefits & Tips

• Save thousands of unnecessary startup cycles to extend both starter motor lifespan and deep-cycle battery health.
• Ideal for heavy city driving and parking garage navigation where frequent idling creates unnecessary thermal strain.
• Tip: Use the included plastic trim tool with steady, even pressure to avoid scratching the dashboard fascia during component access.

Warnings & Reminders

If your dashboard lacks that specific control, this harness is not compatible. Always verify model-year match before purchase. To prevent electrical interference, disconnect the vehicle battery terminal before handling wiring connectors.
