Why Use a Bulkhead Connector?

Passing battery cables through a bulkhead or firewall without a proper connector creates a potential chafe and short circuit risk. A bulkhead connector provides a clean, sealed pass-through point that protects the cable, maintains electrical integrity, and allows the battery cable to be quickly disconnected from outside the car — an important safety feature for race and track use. Many motorsport regulations require a bulkhead connector as part of the electrical safety system.

Fitment & Compatibility

Universal fitment — suitable for any vehicle requiring a battery cable bulkhead pass-through. Mount through a drilled hole in the bulkhead or firewall. Ensure the cable lug used on the M6 side is rated to at least 120A. Always verify current requirements against your vehicle's electrical system before ordering.
