Product Description
The Big7Kits Big 7 Battery Cable Kit replaces the aging factory battery cables on a 2016-2021 Toyota Tacoma 3.5L V6 with a complete, vehicle-specific wiring upgrade. It is a practical option for a stock daily driver with corroded or tired cables, as well as a Tacoma that is being prepared for accessories that place more demand on the electrical system.
Rather than stopping at a typical Big 3 upgrade, this kit also adds upgraded leads for the starter and fuse relay box. An external MEGA fuse is included to support the increased current capacity without routing it through smaller factory fuse-box wiring. Each cable is made from fine-strand pure copper wire, fitted with solid copper terminals, sealed with marine-grade heat shrink, and labeled at the ends to make routing and installation easier to follow.
Before You Buy
Select the wire size based on how the Tacoma is equipped today and where the build is headed. The 2-gauge version is appropriate for a stock truck or modest electrical load. Choose the 1/0-gauge version if you plan to add higher-demand equipment such as a winch, auxiliary lights, an inverter, or a larger audio system. A high-output alternator is not required to install this kit.
