GMR PICKUP INSTALLATION
The MSD GMR pickup can be used with inductive or capacitive ignition types to provide an rpm signal of
30% duration when the ignition coil fires. Two washers are provided with the pickup and must be installed
in one of two positions depending on the type of ignition driving the coil.
Note: For late model applications, it is recommended to have a wiring schematic of the vehicle’s ignition
system.
