Tazer JL Mini Review: The Ultimate Upgrade for Jeep Enthusiasts

Tazer JL Mini Review: The Ultimate Upgrade for Jeep Enthusiasts

As an off-road and overlanding gear hobbyist, I am always on the lookout for products that enhance the performance and functionality of my Jeep. The Tazer JL Mini, a compact and powerful device, has captured my attention for its remarkable capabilities in upgrading the Jeep Wrangler JL, Jeep Gladiator JT, and Jeep Wrangler 4XE models.

Installation and Setup

While learning the navigation of the menu can take some getting used to, one of the standout features of the Tazer JL Mini is its user-friendly installation. Simply plug it into the SGW module above the OBD2 Diagnostic connector, and you're set. This ease of installation is a significant plus for those who prefer a straightforward setup without the hassle of complex wiring.

Customization at Your Fingertips

The Tazer JL Mini shines in its extensive customization options. Whether you're adjusting your tire size to accommodate new off-road tires or tweaking the gear ratios for better performance, this device makes it possible. The Tire Pressure Monitoring System (TPMS) settings are particularly useful for off-road conditions where tire pressure is crucial.

Live Functions for Enhanced Experience

What really sets the Tazer JL Mini apart are its live functions. The Light Show feature, for instance, adds a fun and functional element for off-road visibility and is perfect for car shows or parades. Navigation entry in-motion and the ability to activate the backup camera using turn signals are practical features that add to the driving experience.

Non-Menu Live Functions: A Game Changer

The Non-Menu Live Functions, like the AutoStopStart Disable and AutoTracKill, offer convenience by remembering your settings, saving you the trouble of manually adjusting them every time you start your vehicle.


The Tazer JL Mini is an essential tool for Jeep enthusiasts looking to elevate their vehicle's functionality and performance. Its range of features, combined with ease of use, makes it a valuable addition to any Jeep Wrangler JL, Gladiator JT, or Wrangler 4XE. The ability to customize your Jeep to your off-roading and overlanding needs is truly unparalleled.
