BSNOVT Auto Start Stop Eliminator for Toyota Highlander 2015-2019 — Plug‑In Harness, Reversible A‑Off Delete

How does this eliminator work with my Highlander?

The BSNOVT unit intercepts the start‑stop signal at the switch location so the vehicle behaves as if the auto stop‑start feature is turned off. It does not reprogram the vehicle’s computer or alter engine management; instead it prevents the switch from sending the signal that would engage stop‑start.

• Direct plug‑in harness that connects behind the factory switch.
• No ECU flashing or third‑party software needed.
• Reversible removal returns vehicle to original operation.

Is installation complicated or will I need a mechanic?

Installation is intended to be do‑it‑yourself friendly and requires no splicing or tapping into factory wiring. Using the included disassembly tool, you pop the side cover and top panel around the steering column to access the switch, then plug in the harness and close the trim.

• Tool included for trim removal and safe access.
• No permanent modifications — clips and connector only.
• Typical install takes 10–20 minutes for an average DIYer.

Will this affect other vehicle functions or warranties?

The eliminator is designed to be non‑intrusive: it blocks the stop‑start command without changing other electrical systems. Because the device is plug‑in and removable, it is generally less likely to trigger manufacturer diagnostics than permanent wiring alterations—but check your local dealer warranty terms if concerned.

• Does not alter engine control software.
• Removable to restore factory configuration anytime.
• Low‑impact installation reduces likelihood of diagnostic flags.

What should I expect after installing the A‑Off delete harness?

Once installed, the vehicle will behave as if the Auto Stop‑Start feature has been left off. Note that if the car is turned off for more than about 20 seconds and then restarted, the factory button may need to remain untouched to keep the feature disabled.

• Engine stays running at idle instead of shutting off at stops.
• If the vehicle is powered down for longer than 20 seconds, avoid pressing the button.
• Durable components intended for long‑term use in daily driving.

Who this is for: The BSNOVT Auto Start Stop Eliminator is aimed at Highlander owners (model years 2015–2019) who want a reversible, low‑effort way to stop the auto start‑stop behavior—useful for drivers who tow, use cabin accessories frequently while idling, or simply prefer uninterrupted engine operation. It suits DIY installers who want a plug‑and‑play solution without altering factory wiring, and anyone seeking a robust, easily removable harness that restores the original configuration when needed.
