What are these Wondrous Shiny Bits?
This is the EPIC Wizard Battery Terminal Expansion Kit for your Jeep JL/JT. Briefly, these terminal expansion blocks attach to your battery terminals (and fender ground) to provide a super-clean and safe connection point for all your additional electrical goodies (such as lights, air compressors, fridges, recovery winches, inflatable dolls, auxiliary switch panels, solar chargers, etcetera). 

Ohhh - Give Me More Deets!
The EPIC Wizard terminal expansion blocks attach effortlessly to the OE battery post clamps and grounding studs to provide a clean and efficient distribution of power to all your fancy and unnecessary electrical accessories. We've meticulously crafted the shape and size of these terminal blocks to ensure that we retain the superior vibration resistance of the factory battery post clamps and ensure a seamless integration with the Intelligent Battery System (IBS) sensor for efficient smart alternator charging. 

Each terminal expansion block is precision-machined out of 6100 series aluminum, which is commonly used in the manufacturing of large electrical substation busbars. The parts are then lovingly plated in a thin layer of tin to provide a nice corrosion resistance and to further improve the conductivity of those jumpy little electrons.

How do I install the EPIC Wizard Battery Terminal Expansion Kit?
Check out our installation video for the low-down on what is required for the super-simple installation process. For even greater detail, please see the written instructions (PDF) linked below. Please be aware that the surface finish on each individual terminal block may differ slightly due to variations in the preparation and chemical solutions used in the batch tin-plating of each terminal block.
