{"product_id":"msd-tach-signal-gmr-pickup","title":"MSD Tach Signal GMR Pickup","description":"One example is to connect the GMR, which stands for Giant Magneto Resistive, to a diesel injector current wire. 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.","brand":"MSD","offers":[{"title":"Default Title","offer_id":67864846467240,"sku":"BCCX_8918","price":118.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.truspeedperformance.com\/products\/msd-tach-signal-gmr-pickup","provider":"TruSpeed Performance LLC","version":"1.0","type":"link"}
