C ONNECTING THE S ECONDARY I NDUCTIVE P ICKUP
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.
The inductive pickups contain a fragile Ferrite Core that is sensitive to engine
heat and vibration. Do not drop the inductive pickup or snap the pickup
closed. Use extreme care in handling and placement of the pickups.
1 Clip the secondary inductive pickup around one spark plug wire.
Note: On a wasted spark ignition system, two secondary inductive pickup wires
may be needed.
2 Route the inductive pickup cable clear of devices that produce electronic noise
(spark plug wires, coil wire, coil etc.) to the dyno electronics RPM module.
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.
