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! Just think of the things you can easily accomplish with our GMR Pickup! This little device simply attaches, with no splicing or cutting, to a current carrying wire and turns that information into a 12 volt rpm signal. This signal can be used to activate a shift light, rpm activation switch or a tachometer.\u003c\/p\u003e\u003ch3\u003eFeatures:\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOperates with 5-24 volt input for universal applications\u003c\/li\u003e\n\u003cli\u003eConnect to a diesel injector wire to provide an easy tach installation\u003c\/li\u003e\n\u003cli\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\/li\u003e\n\u003c\/ul\u003e","brand":"MSD","offers":[{"title":"Default Title","offer_id":53101287014687,"sku":"MSD8918","price":118.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0229\/3877\/files\/add2d6c1579e85d0263e9744b1923d40dacde9e6.jpg?v=1792719164","url":"https:\/\/shop.wheelflip.com\/products\/msd-8918-tach-signal-gmr-pickup","provider":"WheelFlip","version":"1.0","type":"link"}
