Toyota Land Cruiser Big 7 Battery Cables Kit (FZJ80 – 1993–1997)
Your 80 Series Land Cruiser is legendary for reliability—don’t let weak factory wiring hold it back. The Big 7 Battery Cable Kit upgrades your FZJ80’s entire electrical foundation with heavy-duty, 1/0 gauge pure copper cables built to handle the toughest trails and the heaviest loads.
What’s Inside the Big 7 Kit?
Most folks know about the “Big 3” upgrade:
Alternator output to battery positive
Battery negative to frame/body
Engine ground to frame/body
Big 7 takes it further. This kit adds upgraded leads to the starter and fuse relay box, plus an external ANL fuse to protect your system from overload. More power where you need it, less chance of electrical gremlins.
Built for the Trail, Not the Driveway
1/0 Gauge SAE-Approved Pure Copper Cable – Maximum conductivity, no copper-clad shortcuts.
Solid-Copper Terminals – Machine-crimped, sealed with marine-grade heat shrink for long-term durability.
Military-Style Battery Clamps – Corrosion-resistant and trail-proven.
Simple Install – Every cable clearly labeled to keep it frustration-free.
Ready for Adventure
This 1/0 GA Big 7 Kit is built for Land Cruisers running winches, lighting, stereos, inverters, or any high-draw accessories. Even if you’re not running them yet, it future-proofs your rig so you’re ready when the upgrades come.
Proudly made in the Pacific Northwest, Big 7 Battery Cable Kits are built by people who know what it means to rely on your Land Cruiser when the road disappears. This is the last battery cable upgrade your FZJ80 will ever need.
