Remote Master Disconnect Kit

The Remote Master Disconnect Kit by Painless Wiring is an essential safety and security component for any custom automotive build, restoration project, or daily driver requiring reliable battery isolation. Designed for mechanics and enthusiasts who demand professional-grade electrical control, this remote mount disconnect switch allows you to cut power to your entire electrical system from a distance—critical for vehicle storage, emergency shutdowns, theft prevention, and extended maintenance work. Whether you're wiring a hot rod, classic restoration, modern swap, or fleet vehicle, this kit eliminates the need to access your engine bay to disable the battery.

Built to handle continuous loads up to 250 amps at 12V, the Remote Master Disconnect Kit features a heavy-duty toggle switch with integrated fuse protection, pre-assembled harness, and crimp terminals ready for installation into any automotive electrical system. The remote mount design separates the switch from the battery disconnect mechanism, giving you flexibility in placement—mount the switch on your dashboard, center console, or firewall for convenient operator access while the main disconnect unit sits near or on the battery. Painless Wiring's engineering ensures low voltage drop and reliable switching performance across repeated cycles, backed by their reputation for quality automotive electrical components used by professional builders and OEM shops nationwide.

Ideal for classic car restorers, street rod builders, racing enthusiasts, and security-conscious vehicle owners, the Remote Master Disconnect Kit works with virtually any 12-volt automotive system—carbureted engines, fuel injection, diesel conversions, and multi-battery setups. Installation is straightforward for anyone with basic wiring knowledge: route the harness from battery to engine bay cut-off point, mount the switch in your chosen location, and connect to ground. The included fuse and terminals protect your investment and prevent accidental short circuits during installation or operation. For show cars, garage queens, fleet vehicles, or any automotive project where total electrical isolation matters, this Painless Wiring disconnect solution delivers professional control and peace of mind.
