Power Upgrade Kit Installation for AC Sport and AC Performance Bikes
NOTE: When installing the power upgrade kit, do not use the console-to-RPM sensor cable (1.11: 740-8928) from the
console kit. This cable is not used when installing the power upgrade kit. Use the console-to-power cable (1.4: 740-8931)
in the power kit to connect the console to the power sensor. Use the RPM-to-power cable (1.5: 740-8932) in the power
kit to connect the RPM sensor to the power sensor; this cable is the shorter cable with a two-pin connector on each end
of the cable.
Repeat Step 1-21 from the console kit installation instructions above with the exception of step 11. Do not remount
the sweat guard.
NOTE: The difference at this point will be that the cable from the console will not be plugged into the RPM sensor. The
RPM sensor cable will have one free end after installing the RPM sensor on the bike and routing the RPM cable through
the cable duct. The console-to-power cable has different lengths of unshielded wires at each end as show below and
has RJ45 connectors on both ends. The end with the shorter length of unshielded wires (right) plugs into the console.
The end with the longer length of unshielded wires (left) is routed through the cable duct and plugged into the power
sensor.
