Toyota Tacoma Big 7 Battery Cable Kit (Gen 2 – 2005–2015)
Your Tacoma might be tough, but the factory wiring is the weak link when you start loading on lights, winches, fridges, and all the overland goodies. The Big 7 Kit upgrades that weak link to something built for the long haul.
What’s Inside the Big 7 Kit?
You know the “Big 3” — alternator → battery, battery → chassis, engine → chassis. We take it further. This kit includes upgraded runs to the starter and fuse relay box, and wraps it all in a clean, smart layout that keeps everything labeled and manageable.
Built for Trail Abuse
1/0 GA SAE-grade pure copper cable — no copper-clad shortcuts
Solid-copper, machine-crimped terminals, sealed with marine-grade heat-shrink
Corrosion-resistant battery clamps, built for grime, sweat, and the elements
Easy install, with each cable clearly labeled to avoid “which wire goes where” headaches
Ready for Tacoma Duty
This 1/0 GA Big 7 Kit is built for Tacomas running winches, off-road lighting, stereos, inverters — or for those planning upgrades in the future. It gives your rig the beefy electrical base it should’ve had from the factory.
Proudly made in the Pacific Northwest, these Big 7 Battery Cable Kits are built by die-hard off-roaders who expect more from their gear. This is the last Tacoma battery wiring job you’ll ever need to do.
