MSD Tach Signal GMR Pickup

Product images may differ from actual product appearance.

Just think of things you can easily accomplish with MSD's new GMR Pickup! 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! There's no easier way to connect an rpm device to a diesel engine! 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 pickup clip and GMR converts this pulsing into a 12-volt signal for a shift light!
