Tectary Auto Start-Stop Eliminator for Ford F-150 2015-2020 — Plug-and-Play A-OFF Memory Harness, No Splice

If your 2015–2020 Ford F‑150 or 2017 Raptor wakes up with the engine stop/start system enabled every time, this compact harness automates the A‑OFF command for you. Designed specifically to match Ford panels with the A‑OFF button in the center, the unit installs without cutting or splicing and works silently in the background to preserve factory features and remote start compatibility.

How does this eliminator work with my F‑150?

The harness intercepts the vehicle signal for the start/stop system and sends the A‑OFF state each time the truck powers up, so you stay in the disabled mode without pressing the button. It uses a stable dual‑core chip and connects to the factory plug, preserving original wiring and settings.

• Compatible with 2015–2020 Ford F‑150 trims (STX, XLT, etc.) and 2017 Raptor when A‑OFF button centered
• Dual‑core control chip for consistent performance
• Maintains remote start and other factory features

Is installation complicated or will it alter my truck?

Installation is straightforward: remove the dash panel with the included pry tool and connect the harness to the original plug. No splicing, programming, or permanent changes to factory wiring are required, and factory settings remain intact.

• Comes with a disassembly tool for safe panel removal
• Plug‑and‑play connection — no cutting or soldering
• Reversible: uninstalling returns the truck to stock configuration

What performance and durability can I expect?

The unit is built from flame‑retardant materials rated for heat and moisture exposure found inside vehicle dashboards. The design focuses on long‑term reliability so the A‑OFF memory works across cycles and temperature changes.

• High‑temperature and water‑resistant housing
• Durable terminals and secure connector mating
• Memory function retains A‑OFF between starts; reset possible by pressing A‑OFF

Will this unit work with features like remote start or cause error messages?

No — the Tectary harness is engineered to be compatible with factory systems so it shouldn't interfere with remote start, diagnostics, or other onboard electronics. If the vehicle does not accept the signal, a quick reset and engine restart typically resolves the issue.

• Does not impact remote start capability
• Designed to avoid fault codes; follow reset instructions if needed
• If it doesn’t work initially, power cycle the vehicle to reinitialize the harness

Who is this for: The Tectary Auto Start Stop Eliminator is aimed at Ford F‑150 owners (2015–2020) and 2017 Raptor drivers who prefer to keep the engine stop/start system off without pressing the A‑OFF button every time. It’s ideal for technicians, DIY installers, and drivers who want a reversible, factory‑friendly solution that installs quickly and runs reliably.
