2018-2024 Jeep Wrangler JL Auto Start Stop Eliminator | Plug & Play

This plug-and-play memory harness is for the 2018–2024 Jeep Wrangler. It stores the last stop-start setting you chose, so if you turned Engine Stop-Start (ESS) off on one drive, it stays off the next time you start the engine. It plugs in line with the factory connector named in the instructions, using factory-style plugs on both ends, so nothing is cut or spliced.

You can still use the original button at any time. Whatever you select last is what the module repeats on the next start. Take the module out and the vehicle behaves exactly as it did from the factory.

Covered model years

Listed applications (each row is a 100% fitment match for the factory connector this part uses):

• Jeep Wrangler: 2018–2024

Trim is not listed separately. Any trim in these years with factory stop-start and the pictured connector is covered.

What the factory system does

Each start of the Jeep Wrangler begins with Engine Stop-Start (ESS) enabled. The switch on the dash can disable it, but only until the key is cycled. This module records the switch position and repeats it after the restart, which is the entire job it does.

Before blaming the module

A dead or weak battery, a charging problem or an unrelated module fault will change how Engine Stop-Start (ESS) behaves with or without this part installed. Scan the vehicle for stored codes, test the battery and confirm the system works normally with the factory button before installation. That baseline makes any later issue easy to pin down.

What to expect

• It remembers the last stop-start setting through a key cycle.
• It leaves the factory button working, so you can turn stop-start back on whenever you want.
• It does not change engine power, transmission shifts, emissions calibration or fuel trims.
• It does not write anything to the vehicle's modules, and removing it restores the stock default.

Keep the battery healthy

Most stop-start systems watch battery condition closely through a sensor on the negative terminal. When the battery ages, the system quietly stops auto-stopping long before the battery fails to crank. Keeping the original battery type (AGM or EFB) and a clean, tight ground connection avoids a lot of confusion about why the system behaves differently from week to week.

When the engine will not auto-stop anyway

The factory system will skip an auto stop for many reasons: battery charge below its threshold, cold coolant, high climate-control load, a steep grade, the hood or driver door open, or a 4WD or tow mode on vehicles that have them. Those checks stay in control after this module is installed. It does not force stops and it does not bypass any of those safety inputs.

Where it connects

It plugs in line with the factory connector named in the instructions, using factory-style plugs on both ends, so nothing is cut or spliced. Work with the ignition off. Seat each connector until its lock engages, then secure the module with the supplied ties or tape so it cannot rattle or touch pedals, steering parts or anything hot. Start the vehicle, press the stop-start button once, then restart to confirm the choice is held.

Where owners notice the difference

Stop-start saves the most fuel in long idles, but plenty of drivers would rather keep the engine running. Common reasons: towing or hauling, where an engine restart under load is unwelcome; drive-thru lines and parking lots, where the engine cycles on and off every few feet; hot days, when the A/C compressor stops with the engine on many vehicles; and stop-and-go traffic where the restart delay is noticeable when pulling into a gap. On a daily driver, any of these can mean a button press at the start of nearly every drive.

Fitment check

• Model year and model match a row in the table above (2018–2024 Jeep Wrangler).
• Your Jeep Wrangler has the factory stop-start button. Base trims or engines without stop-start have nothing for the module to remember.
• The connector at your install point matches the one in the product photos.
• No aftermarket remote start, alarm or gateway bypass is wired into the same circuit. If one is, email support before ordering.
• The battery and charging system test good and no warning lights are on.
• If you are unsure, send your VIN to support@automotivebypass.com and we will confirm fitment.
