purchased from your dealer. Carefully follow the instructions provided with the tool if you need to remove
a pin from the connector.

Due to the various jack shaft diameters the collar which holds the magnet must be purchased separately. If
you did not purchase a jack shaft collar contact your dealer for more information.
Install the collar on the jack shaft. Make sure the collar fits snug and cannot slip. If the collar does not fit
properly contact your dealer to obtain a correctly sized collar. Mount the sensor so that it is directly over
the collar and has 0.050” to 0.075” air gap. Connect the purple wire from the dash port A pin 12 to the red
