3 Wiring Strategies

The Frankenrunner can be hooked up to the controls of an ebike system in one
of three ways. It can be connected under the full control of a V3 Cycle Analyst,
under the control of a 3 rd party display, or "headless" with no display at all.

3.1 Cycle Analyst Based Hookup

The setup using the latest V3 Cycle Analyst (CA3-WP) provides the most
versatility with mode presets, customizable PAS behavior, advanced regen
features, and easy performance adjustments on the road. In this arrangement, all
throttle, ebrake, and PAS or torque sensors are plugged in directly to the Cycle
Analyst. The Cycle Analyst is responsible for determining the desired ebike
behavior and sending a suitable throttle command to the controller.
The 6 pin PAS plug of the controller is typically not used in this arrangement
except as a possible Fwd/Rev input source. The 9 pin Mains cable either can be
left unterminated, or it can be used as a power tap for running rear lights, using a
9 to 2 pin Power Adapter cable.
3.2 3 rd Party Display Hookup
The Frankenrunner can be used with certain third party displays (from King
Meter, Star-Union, Bafang etc.) that communicate using the KM5s digital
protocol. This is achieved with a 9 pin Mains cable harness which splits out the 9
signals into separate plugs for throttle, display, ebrakes, and front light, along
