The ZAutomotive Tazer JL Mini is a plug-and-play electronic programmer for 2020–2026 Jeep Gladiator JT models that unlocks over 70 vehicle settings and live driving features directly through your dash display. It plugs into the Security Gateway (SGW) module above the OBD2 port and is especially popular for permanently disabling Auto Stop/Start after an aux battery delete and recalibrating the truck for larger tires. ¹⁾²⁾³⁾

ZAutomotive Tazer JL Mini Programmer $334.86 ⁴⁾

• Compatibility: Fits all 2020–2026 Jeep Gladiator JT engines and trims, including 3.6L Gas, EcoDiesel, and export variants.

Vehicle Settings (Saved to the Jeep's Computer)

These settings are programmed with the engine off and ignition in the “RUN” position, and they stay active even if you unplug the Tazer.¹⁰⁾

• Tire & Gear Calibration. Adjusts tire size up to 41 inches, updates axle gear ratios, and changes transfer case low ratios so your speedometer and transmission shift points stay accurate. ¹¹⁾¹²⁾
• TPMS Adjustments. Lowers or raises the Tire Pressure Monitoring System warning thresholds between 25 PSI and 85 PSI, or disables the system completely.¹³⁾
• OEM Upgrade Activation. Enables factory add-ons without a dealer visit, including LED headlights/taillights, auxiliary switch banks, trailer brake controllers, and the 115V pickup bed outlet. ¹⁴⁾
• One-Touch Unmarry. Reverts all modified computer settings back to factory stock in one step before dealership service.^{15) 16)}

Live Functions (Active While Plugged In)

These features run continuously while the module stays connected to your Jeep.¹⁷⁾

• Auto Stop/Start Memory. Automatically remembers your last ESS button state so you do not have to press it every time you start the truck.
• Gladiator-Specific Lighting. Turns off the license plate lights automatically when shifting into reverse to eliminate backup camera glare, and lets you turn on the bed and reverse lights from your keyfob.
• Off-Road & Winch Controls. Engages Rubicon/Mojave axle lockers in 2WD and 4Hi on demand, disconnects the sway bar in 2WD up to 30 mph, and raises engine idle up to 2,000 RPM for winching.
• Anti-Theft & Convenience. Adds a steering wheel button PIN lock before driving, disables the three-horn honk when exiting a running Jeep, and activates the backup camera when using turn signals (TurnCAM). ¹⁸⁾

Installation & Dealership Tips

• Plug-In Location. Remove the driver-side knee panel under the steering wheel and locate the two SGW connectors just above the OBD2 port. Unplug both cables from the factory module and snap them directly into the Tazer JL Mini.
• SGW Extension Cable. The factory SGW wires are short and tucked tightly behind the dash. Adding an optional SGW extension cable from ZAutomotive makes unplugging the Tazer before dealer visits much easier.
• Power-Down Cycles. After changing any Vehicle Settings, perform two full sleep cycles (turn ignition off, open and close the driver door, and wait 60+ seconds for the dash screen to go black) so the body control module saves your changes.¹⁹⁾

Drivetrain, Tires & Axle Swap Mods

These Vehicle Settings reprogram your Gladiator's computer to accept aftermarket hardware without throwing dashboard warning codes. • Tire Size & Gear Ratio. Adjusts tire diameter up to 41 inches, updates axle gear ratios (such as 4.56, 4.88, or 5.13), and modifies transfer case low-range ratios to fix speedometer and automatic transmission shift points.

To set up your ZAutomotive Tazer JL Mini on a Jeep Gladiator, plug the module into the Security Gateway (SGW) wires behind the driver-side knee panel, Marry it to your VIN, program your settings, and run two full sleep cycles so the computer saves your changes ZAutomotive Tazer JL Mini User Guide.

Step 1: Firmware Update (Before Installing)

• Download the Utility. Install the free ZPU (ZAutomotive Programming Utility) on a Windows or Mac computer before heading to your Jeep. • Update the Module. Connect the Tazer JL Mini to your computer using the included USB cable and install the latest firmware so all current Gladiator menus and bug fixes are loaded.

Step 2: Physical Plug-In Installation

• Remove the Knee Panel. Pull straight back on the plastic trim panel beneath the steering wheel to release the retaining clips, then let it hang down out of the way. • Locate the SGW Module. Look just above and to the left of the OBD2 diagnostic port for a small black module with two side-by-side wire plugs (one 12-pin and one 8-pin). • Swap the Connectors. Press the locking tabs on both factory plugs to release them from the SGW module, and snap them directly into the matching ports on the Tazer JL Mini. • Secure the Module. Tuck the Tazer (and optional SGW extension cable, if used) safely above the knee panel using a zip tie so it cannot interfere with your steering column or pedals.

Step 3: Marry the Tazer to Your Gladiator

• Enter RUN Mode. Without pressing the brake pedal, push the Start/Stop button twice until the ignition is in ACC/RUN (engine off, dash cluster lit up). • Navigate the Dash Menu. Use the Up and Down arrows on the left side of your steering wheel until your instrument cluster displays the Audio screen. • Open the Tazer Menu. Press and hold the Left Arrow on the steering wheel, then tap the Cancel (cruise control) button to enter the Tazer interface. • Select Marry. Using the same Left Arrow + Cancel combination to advance through menus, navigate to Marry and select it with Left Arrow + Cruise On/Off (Res). Wait about 15 seconds while it backs up your factory configuration.

Step 4: Program Settings & Complete Sleep Cycles

• Adjust Your Settings. Scroll through the Tire, Gear, TPMS, and Lighting menus using Left Arrow + Cancel, and change values using Left Arrow + Cruise On/Off. • Perform Two Full Sleep Cycles. Changes will not stick—and warning lights may stay on—until the Jeep's Body Control Module resets twice:

1. Turn the ignition completely OFF, open the driver's door, close it, and wait 60+ seconds until the instrument cluster screen goes completely dark.
2. Press Start/Stop twice back to RUN (engine off), wait 10 seconds, turn ignition OFF, open and close the driver's door, and wait another 60+ seconds for the dash to go dark.

• Start the Engine. Start your Gladiator normally and verify that your new settings are active and no dashboard warning lights remain.

Important Dealership Tip

• Unmarry Before Service. Always navigate to the Unmarry option and run two sleep cycles before taking your Gladiator to a dealership so factory diagnostic tools can communicate with your truck and your settings are not overwritten. Would you like the specific steering wheel button shortcuts for operating Live Functions on the trail (like Winch Mode, Light Show, or 2WD Lockers), or help troubleshooting a specific warning light after setup?
