  3. What is the difference between the circuit board with LED's and without LED's?  The circuit board with the LED's has the Diagnostic LED circuits installed. The circuit board without the LED option does not have the Diagnostic LED circuits installed.
  4. Will this work with my original tachometer and gauge cluster?  Yes. Installation is simple unbolt the old circuit board from the tachometer, and bolt the new circuit board on to the tachometer.
  5. Will the LED's affect night instrument lighting? No the LED's are dim and will not affect instrument panel lighting.

LED Indicators option (If selected when ordering):

If you ordered the LED indicator option, the LED's can be used to help diagnose Tachometer circuit problems. They indicate if the power circuit is completed and if the RPM signal circuit is completed respectively.

For example, If the RPM signal was nonexistent, the LED would not light. If the signal was intermittent, the LED may flicker. If the circuit board was not receiving power, the Power LED indicator would not light. In this way the LED's are useful to help with diagnosing tachometer problem related to the power and RPM circuits.
