Honda S2000 battery disconnect switch kit with loom

Every S2000 owner who's deep into a build, preparing for a track day, or storing the car over winter knows the frustration: fumbling with a wrench on the battery terminal, scratching the tray, risking a loose ground, and ending up with a cable zip-tied to nowhere. This kit eliminates all of that — permanently.

Key Benefits

• Three precision-engineered mounting plate options — each cut to identical S2000 fuse box geometry, differing only in material character and weight

• 300A continuous / 450A surge-rated disconnect switch — engineered for motorsport electrical loads, not undersized consumer hardware

• 50mm² heavy-gauge negative cable — substantially thicker than OEM spec — handles high electrical loads and ensures reliable cold starts

• All terminals professionally crimped and ready to install — no soldering, no guesswork, no additional hardware sourcing

• Zero dashboard or chassis modification required — mounts to existing fuse box area geometry

• Track day compliant — meets common motorsport and circuit regulations requiring accessible battery isolation

• Anti-theft and parasitic drain protection as a passive benefit of daily or storage use

• Laser engraving options: Tsunami | Tokyo Sunset (specify variant at checkout)
