Today I’m upgrading my Jeep Cherokee’s electrical system with the Big 7 kit from JeepCables.com — because crusty factory wiring and weak voltage just weren’t cutting it anymore. This kit replaces your major power and ground cables with beefy, high-quality wires designed specifically for the XJ. In this video, I’ll show you what comes in the kit, how I installed it, and why it’s one of the best upgrades you can do if you’re running accessories, lights, or just want better reliability.
