1
Cut a one inch strip of reflective tape from the roll provided.
2
Clean a flat section of the harmonic balancer. Attach the strip of reflective tape.
Note: High RPM engines will require a longer piece of reflective tape; use a
1.25-1.5-inch strip of tape.

3
Attach the optical sensor lead to the hardware stack. You need to remove any
inductive leads from the RPM module if installed.
4
Attach the small power lead from the optical sensor lead to the CPU module.
