The badges are DEFINITELY high quality. They come in a plastic wrapper inside the cardboard envelope so they’re not going to get scratched otw to you.

Big 7 Battery Cable Kit
For 1984–1989 1st Gen Toyota 4Runner & 1984–1988 2nd Gen Toyota Pickup
Overview
This Big 7 Battery Cable Upgrade Kit is designed for 1984–1989 Toyota 1st Generation 4Runner and 1984–1988 Toyota 2nd Generation Pickup to replace aging factory wiring and improve overall electrical system performance.
Over time, original battery cables degrade due to heat, corrosion, and environmental exposure. This kit upgrades critical power and ground connections to restore reliability, improve current flow, and support both stock and modified electrical systems.
What Is the Big 7 Upgrade
The Big 7 system expands on the traditional “Big 3” electrical upgrade by increasing current capacity across all major power and ground connections in the vehicle.
This kit upgrades:
- Alternator to battery positive cable
- Battery negative to chassis ground
- Engine block to chassis ground
- Starter power cable
- Fuse and relay box power leads
- Additional fused power connection for improved load handling
An included external ANL fuse and holder helps manage increased current safely without overloading factory wiring.
Performance Benefits
Upgrading your battery cables improves electrical efficiency across the entire vehicle.
Key benefits include:
- Faster and more reliable engine starts
- Improved battery charging performance

- Increased reliability for aging electrical systems
- Support for accessories such as winches, lighting, and audio systems
This upgrade is beneficial for both stock vehicles and modified builds.

Construction features:
- Pure copper, fine-strand SAE-approved cable

Each cable is labeled for straightforward installation.
Cable Size Options

Choosing the correct size helps ensure proper electrical performance and system efficiency.
