RVMARINEPAT Auto Start Stop Eliminator for Jeep Wrangler JL & Gladiator JT — 2018–2024 Plug-and-Play 12‑Pin Harness, Error-Free A‑

RVMARINEPAT's Auto Start Stop Eliminator is a plug-and-play 12-pin harness that permanently defaults the A-OFF/ESS system to OFF in compatible 2018–2024 Jeep Wrangler JL and 2020–2024 Gladiator JT models, without error codes.

If you’re tired of the factory stop/start re-engaging every time you turn the ignition, this compact module offers a straightforward electrical bypass that keeps the feature disabled by default while preserving other vehicle electronics and remote start functionality. The kit plugs into the vehicle’s Security Gateway Module (SGW) and is designed for owners who want a reliable, reversible change without complicated programming or dashboard surgery.

How does this eliminator install so quickly?

Installation is intended to be simple and fast: the harness connects to a factory 12-pin SGW connector so no splicing or special tools are required for most vehicles. Two common module locations cover the majority of model years and trims, keeping the work under five minutes in many cases.

• Includes a T-harness with a matched 12-pin connector for true plug-and-play
• Module typically located behind lower steering column or above driver-side floorboard
• No dashboard removal required for most models; visual guide included
• Step-by-step illustrated instructions to reduce install time

Will this trigger errors, void warranty, or interfere with other systems?

The harness is engineered to communicate with vehicle electronics in a way that avoids diagnostic trouble codes and should not disrupt factory features like remote start. It does not alter ECU programming; instead it presents a compatible signal to the SGW so the vehicle registers the A-OFF/ESS state without throwing warnings.

• Designed to prevent check-engine or warning lights related to stop/start
• No reprogramming of vehicle software required
• Leaves unrelated systems—infotainment, A/C, safety features—unchanged
• Reversible: remove the harness to restore factory behavior

What driving differences should I expect after installation?

With the stop/start system defaulted to OFF, your engine will not auto-shut when coming to a complete stop unless you manually re-enable it. This change yields a steady cabin temperature and uninterrupted power to accessories like dash cams, and eliminates the occasional restart jerks some drivers notice.

• Consistent A/C performance at idle and in traffic
• Smoother stops without automatic engine restarts
• Continuous power to accessories and recording devices
• Manual reactivation still available via the factory A-OFF/ESS button

Who is this for: This harness is aimed at Jeep Wrangler JL (2018–2024) and Gladiator JT (2020–2024) owners who prefer to keep auto start-stop off by default for comfort, accessory power, or to reduce cycling wear. It’s ideal for do-it-yourself installers and professional shops wanting a tidy, reversible solution—but make sure your vehicle uses the 12-pin SGW connector shown in the product photos before purchasing. If your Gladiator uses an 8-pin plug or a different gateway, this specific kit won’t fit.
