Product details
Your preferred setting, every drive
The 4D Tech Start / Stop Eliminator remembers your Auto Start / Stop setting and restores it when you start your F-150. Choose OFF to keep the engine running at stops, or choose ON to use the factory system. Your dashboard button continues to work normally, and remote start is retained.
Leave the device plugged in. It operates through the diagnostic port while installed; it does not make programming changes to your truck.
Check your fitment
Fits 2015–2020 Ford F-150, including all trim levels and Raptor equipped with factory Auto Start / Stop. Match your model year before ordering.
Plug into the diagnostic port
No tools or trim removal are required. Watch the complete installation video.

- Locate the diagnostic port. Find it below the steering wheel, as shown above and in the video.
- Plug in the device. Seat it securely in the port. The video shows a brief blue light when a connection is established.
- Choose your setting. Start the truck and use the factory Start / Stop button to select ON or OFF.
- Leave it connected. The device remembers your selection between drives while it remains plugged in.
Removing the device restores normal factory operation. A paper quick-start guide is included. Contact our support team if you need help.
Does it need to stay plugged in?
Yes. This is a leave-in memory device, not a programmer that you unplug after installation. It occupies the diagnostic port while in use. Remove it when the port is needed for vehicle diagnostics, then reconnect it afterward.

As advertised
Worth the money to never have hit auto start stop switch every time you start vehicle. Seen all types of solutions. Trailer plugs, devices hooked directly to switch. This is simple and it works.
