Toyota Tacoma Big 7 Battery Cable Kit (Gen 1 – 1995–2004)
Your first-gen Tacoma has earned its reputation — simple, tough, and dependable. But when it comes to the factory wiring, “dependable” isn’t exactly the word we’d use after two decades of heat, corrosion, and trail abuse. The Big 7 Kit fixes that weak link and gives your Tacoma the solid electrical foundation it deserves.
What’s Inside the Big 7 Kit?
You’ve heard of the “Big 3” — alternator → battery, battery → chassis, engine → chassis. We take it further. The Big 7 Kit adds upgraded runs to the starter and fuse relay box, along with clean routing and labeling so everything installs exactly where it should.

-
Solid-copper, machine-crimped terminals, sealed with marine-grade heat-shrink

Clean, labeled install — because electrical upgrades shouldn’t feel like a puzzle
