Toyota 4Runner Big 7 Battery Cable Kit (Gen 3 – 1996–2002)
Your third-gen 4Runner is tough, reliable, and a trail-proven legend. But the factory wiring wasn’t designed to handle winches, lighting setups, fridges, or other high-draw accessories. Voltage drops, dim lights, and sluggish starts are a sign it’s time for an upgrade — the Big 7 Kit is your solution.
What’s Inside the Big 7 Kit?
You know the “Big 3” — alternator → battery, battery → chassis, engine → chassis. We go further. The Big 7 Kit upgrades those connections and adds dedicated runs to the starter and fuse relay box, all routed cleanly with labeled cables for a fast, frustration-free installation.

Available in 2 GA, 1/0 GA, or 2/0 GA to match your build’s power needs
