Note: Sensors should be protected against strong
light because they have an optical measuring
system which under the influence of external
light may not work correctly.
Note: when installing on fuel injected engines its not
necessary to use Tacho pulse limiter and green wire
can be connected directly to the Tacho exit from the
engine shifters
