If the primary wire is not accessible connect a secondary inductive pickup to an
available spark plug wire. The secondary inductive pickup cannot be in contact with,
or it’s connecting wire be crossing, other engine electrical wires or stray RF
interference may result.
You will need the following part:
• DE100-109S Secondary Inductive Pickup (2)
1 Clip the secondary inductive pickup around one spark plug wire.
2 Route the inductive pickup cable to the RPM Module making sure the cable is
clear of devices that produce electronic noise (spark plug wires, coil wire,
coil etc.).
Note: Inductive pickup placement is important. Position the inductive pickup so
that it is not making contact with any other spark plug wires. Separate the spark
plug wire from the spark plug wire bundle for proper operation.
Note: You must ground the vehicle to the dyno for the electronics to function
properly.
Note: When using one secondary pickup, disconnect the other pickup from the
dyno electronics.
