Toyota 4Runner Big 7 Battery Cable Kit (Gen 5 – 2010–2024)
Your fifth-gen 4Runner is built for adventure, but the factory wiring wasn’t designed to keep up with winches, lights, fridges, or overland accessories. Voltage drops, dim lights, and sluggish starts are a sure sign it’s time for an upgrade — enter the Big 7 Kit.
What’s Inside the Big 7 Kit?
You know the “Big 3” — alternator → battery, battery → chassis, engine → chassis. We go beyond. The Big 7 Kit adds upgraded runs to the starter and fuse relay box, all routed cleanly with labeled cables for an install that’s as smooth as your 4Runner’s ride.
