We don't stop there though. Our \"Big 7\" kits also include the leads to the starter and the fuse relay box, as well as adding an external fuse to avoid routing the increase in current capacity through the smaller fuse box wiring. It’s really one of the first mods you should do to any Jeep!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat makes these cables so special?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWe're nerds for specs and finer details around here. None of that CCA (copper-clad aluminum) that's used in inferior products, or stereo installations. We only use fine-strand, SAE (Society of Automotive Engineers) approved, pure copper cable. Then using a powerful electromechanical crimping machine, we crimp each solid-copper end, and finally finish the construction by adding a environmental seal made of marine grade heatshrink meeting MIL-I-23053\/4. This same high-quality construction is ideal for \u003ca href=\"https:\/\/www.big7kits.com\/collections\/jeep-grand-cherokee-wj-1999-2005\"\u003eJeep Grand Cherokee WJ (1999–2005)\u003c\/a\u003e owners looking for a durable, long-lasting electrical upgrade built to handle demanding conditions. Also included are military style corrosion resistant battery connections and a MEGA fuse and holder. To make the entire install simpler, every end will be labeled for ease of installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need a bigger alternator to run these cables?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. Every vehicle can benefit from our \"better than factory\" cables. The years, along with environmental damage from rain\/salt water\/corrosion, can greatly impact your electrical system. Our customers have consistently reported that their vehicle starts faster, charges the battery better, and many times cured electrical gremlins that were brought on by compromised wiring.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eI've changed my mind!
