This kit provides a simple, visual way to confirm whether the engine control wiring is delivering the correct pulses. Compact and easy to use, the set plugs into factory harnesses and uses LED indicators to show whether circuits are pulsing normally, steady, or absent.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I use the noid light to check my fuel injectors?\u003c\/h3\u003e\n\u003cp\u003eLocate and unplug the electrical connector from the injector, then plug the matching noid light into the harness. Crank the engine for a few seconds; a flashing LED shows the ECU is sending proper pulses. A steady-on or non-illuminated light signals a wiring or control problem.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUnplug injector connector and insert noid light\u003c\/li\u003e\n  \u003cli\u003eUse extensions when access is tight\u003c\/li\u003e\n  \u003cli\u003eCrank engine briefly to observe LED behavior\u003c\/li\u003e\n  \u003cli\u003eFlash = proper pulse; steady or dark = fault\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan this kit diagnose idle air control (IAC) issues?\u003c\/h3\u003e\n\u003cp\u003eYes — the included IAC signal tester replicates the electrical load and checks the IAC circuit while the engine idles. When the IAC is operating correctly, multiple LEDs will flash to indicate varying duty cycles; missing flashes point to bad wiring, a failed valve, or control module issues. Testing is noninvasive and avoids disassembling the valve during initial troubleshooting.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDisconnect IAC harness and plug in the IAC tester\u003c\/li\u003e\n  \u003cli\u003eCreate a load or let engine idle for observation\u003c\/li\u003e\n  \u003cli\u003eTwo or more flashing LEDs indicate proper signal\u003c\/li\u003e\n  \u003cli\u003eSingle or no flash suggests a fault needing further testing\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich vehicles and connectors are supported by the kit?\u003c\/h3\u003e\n\u003cp\u003eThe set is designed to work with common automotive injector and IAC harness types across many gasoline engine platforms.
