It is supplied with an extended 96-inch lead to give you routing flexibility in engine bays and is intended for GM LS engines using the 4-terminal flat alternator connector. The assembly removes the need for custom splices or separate resistors when using an engine control module (ECM) is not an option.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this pigtail make alternator wiring simpler?\u003c\/h3\u003e\n\u003cp\u003eThe JUNRUO pigtail bundles the connector, resistor and long lead into one plug-and-play unit so you can replace a worn harness or adapt a 12V signal without extra components. Installation is straightforward: plug into the alternator's 4-pin flat connector and route the 96\" lead to your switched 12V source or ignition feed.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrated in-line resistor reduces raw 12V to the alternator’s expected signal voltage.\u003c\/li\u003e\n  \u003cli\u003eFactory-terminated connector fits GM LS 4-terminal flat alternators.\u003c\/li\u003e\n  \u003cli\u003e96\" lead length provides flexible routing and easier connections to the fuse box or ignition feed.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this work with my engine and alternator model?\u003c\/h3\u003e\n\u003cp\u003eThis pigtail is designed for 1999 and newer GM LS-series engines that have the 4-pin flat alternator plug common to many Gen III alternators.

Because the resistor is inside the pigtail, you avoid fabricating a separate resistor circuit or modifying the alternator; that keeps the installation cleaner and reversible.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReady-to-install; no soldering or separate resistor needed for compatible setups.\u003c\/li\u003e\n  \u003cli\u003eHelps protect alternator control by delivering the proper 'on' signal voltage.\u003c\/li\u003e\n  \u003cli\u003eDurable connector and insulation for typical under-hood environments; secure routing recommended away from extreme heat sources.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: mechanics, hot-rodders, engine-swappers and DIY car owners who need a reliable alternator signal pigtail for GM LS Gen III engines. If you are replacing a damaged plug, retrofitting a non-ECM setup, or wiring an alternator that requires a stepped-down \"on\" signal, this JUNRUO 96\" resistor wire pigtail removes guesswork and avoids custom resistor installations.
