Tach Signal GMR Pickup MSD8918

Tach Signal GMR Pickup 8918 MSD8918 Converts Coil's primary wire to 12 volt signal TACH SIGNAL GMR PICKUP 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.
