Installation Instructions for DYNA Ignition System without
Tach Signal Output
Locate the wire that runs directly from the battery to positive side of the coil. If
you have two coils you must have two separate wires run from the battery to
each coil. Disconnect the wire between the battery and one of the coils. Run
the wire from the battery thru the sensor with the yellow dot side entering first.
Make 4 passes with wire thru the hole and connect the wire back to the positive
side of the coil as shown below.
If your ignition system has a digital tach output do not use this sensor. Contact
Racepak to obtain the correct RPM interface. If you ignition does not have a
digital tach output follow the instructions below.
