Dual HEI connector clips on to your HEI's tachometer and battery terminals. This connector eliminates the need to use spade terminals that can wiggle loose or fall off. The color coded pigtails make it easy to identify your tach and battery wiring. The Dual HEI connector is made of a high temperature plastic that is rated at over 250° Fahrenheit. The durable plastic connector is molded to match the terminals and features a built in clip to hold the terminals in place. The red 12 gauge battery and green 14 gauge tachometer wires are easy to identify and splice into. The brass terminals ensure a positive connection for a strong tach signal and correct battery volt
