This will produce a signal that can be used to trigger a tachometer or shift light! Another example is on late-model engine equipped with a coil-on-plug ignition system. One of the coil's primary current wires is simply routed into the pickup clip and GMR converts this pulsing into a 12 volt signal for a shift light!\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures \u0026amp; Benefits\u003c\/strong\u003e\u003cbr\u003eClip to a coil pack primary lead to produce a stable 12-volt square wave for a tach, shift light or RPM-activated accessory\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e Converts a low-voltage, high-current pulse to a clean 12-volt square wave with no wire splicing required.\u003c\/p\u003e\u003ch3\u003eProduct Video\u003c\/h3\u003e\u003cdiv style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:1em 0;\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/v2AgK33nolY\" title=\"Product video\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen style=\"position:absolute;top:0;left:0;width:100%;height:100%;\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e","brand":"MSD","offers":[{"title":"Default Title","offer_id":44472440160321,"sku":"8918","price":133.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/2500\/9217\/files\/8918_01.jpg?v=1787649664","url":"https:\/\/www.theefistore.com\/products\/msd-8918","provider":"The EFI Store","version":"1.0","type":"link"}
