USCAR fuel injector connector pigtail. One connector with pigtails. Priced individually (Order quantity 4 for a set of 4 fuel injectors). This injector pigtail connects to USCAR style injectors (like the Injector Dynamics ID725, ID1000, ID1050x, ID1300x, ID1700x) and allows you to splice into your factory fuel injector wires easily. We recommend that you solder and heat shrink your connections.
