Wire Harness - Two Pin Battery

The Wire Harness - Two Pin Battery by FAST Electronics is a purpose-built ignition wiring harness engineered for high-performance engine management systems and custom vehicle builds. This 36-inch harness connects the battery to two-pin Crane ignition modules, delivering the clean, noise-free signal path that modern EFI conversions and race engines demand. Whether you're retrofitting a carburetor engine with electronic ignition or upgrading a classic hot rod, this harness eliminates the complexity of aftermarket wiring by providing a direct, factory-quality connection.

Designed specifically for Crane two-pin ignition systems, the harness uses shielded conductors and a precision-molded two-pin connector to reduce electromagnetic interference—critical for maintaining stable spark timing under boost or high RPM conditions. The 36-inch length provides flexible routing through engine bays of varying sizes, from compact imports to full-size trucks, without requiring splices or extension modifications. Weighing just 0.32 lbs, the compact construction fits easily into tight spaces while the durable insulation handles underhood heat cycles without degradation.

This harness is ideal for engine builders, performance shops, and enthusiasts installing Crane electronic ignition upgrades on street engines, drag cars, or vintage restorations. Installation is straightforward: connect one pin to battery positive (with appropriate inline fuse protection) and the other to ground or the module return terminal, depending on your specific Crane ignition model. Always consult your ignition module documentation to confirm pinout before final assembly, and ensure all connections are fully seated to eliminate intermittent spark issues.
