Tach Signal GMR Pickup

Converts Coil's primary wire to 12 volt signal

Just think of things you can easily accomplish with our GMR Pick-Up! This little device simply attaches, 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. One example is to connect the GMR, which stands for Giant Magnetoresistive, to a diesel injector current wire. This will produce a signal that can be used to trigger a tachometer or a shift light! Another example is on a late-model engine equipped with a coil-on-plug ignition system. One of the coil's primary current wires is simply routed into the Pick-Up clip and GMR converts this pulsing into a 12-volt signal for a shift light!

• Clip to a coil pack's voltage wire to produce a common 12-volt signal for a tach, shift light or rpm device.
• Connect to a diesel injector wire to provide an easy tach installation.
• Operates with 5-24 volt input for universal applications
