Blade Terminal Female Insulated 16-14 20pk

The Blade Terminal Female Insulated 16-14 20pk from Allstar Performance is the go-to connector solution for automotive wiring harnesses, electrical repairs, and custom vehicle modifications. Whether you're rewiring a classic restoration, upgrading an engine harness, or building a custom electrical system, these insulated blade terminals provide secure, corrosion-resistant connections that withstand vibration and temperature cycling in demanding underhood environments. A 20-pack ensures you have adequate spares for multi-circuit projects or future maintenance needs.

Each blade terminal is engineered to accommodate 16- to 14-gauge wire, offering a snug, low-resistance crimp connection that minimizes voltage drop across electrical circuits. The insulated vinyl sleeve isolates the terminal from adjacent conductors and chassis ground, reducing the risk of shorts and arcing that can damage sensitive engine control modules or ignition systems. The female blade design mates with standard male blade connectors found on relays, switches, and distribution blocks, making these terminals compatible with most domestic and imported vehicle electrical systems. Proper crimping with a quality crimper ensures a gas-tight seal that resists oxidation and maintains electrical integrity through thousands of engine run hours.

Professional mechanics, restoration shops, and performance builders rely on Allstar Performance terminals for OEM-level reliability in custom harness assembly and repair work. These connectors are essential for fuel injection retrofits, auxiliary lighting circuits, turbocharger control wiring, and standalone ECU installations where factory connectors are unavailable or incompatible. Installation requires a crimper designed for blade terminals—precision matters, as a loose crimp creates resistance heating that can melt insulation or ignite fuel vapor in the engine bay. Always verify wire gauge against the terminal rating and use heat shrink tubing over the connection for additional environmental protection in moisture-prone areas.
