Page 3: Introduction
Figure 1: Example of a Mains Harness (Green) Grin’s Main9 Superharness is a device that looks similar to this for use with our V6 Phaserunner/Baserunner controllers. Unlike conventional harnesses, it contains an internal circuit board to provide extra functionality. -
Page 4: Connectors
Superharness User Manual Rev P3 2 Connectors The Superharness uses overmolded Higo equivalent ebike connectors for all signal lines. These plugs are waterproof and reliable when connected, but it is possible to damage the pins by forcing them in the wrong way. Be sure to align the arrows and double check that you are matching the same pin count on the male and female sides. -
Page 5: Dc Light Plugs
Superharness User Manual Rev P3 The display plug uses a 5 pin Higo connection* wired in one of the more common of several known pinout standards. *Note, some displays are using the same 5 pin connector but with different choice of the pin assignments. -
Page 6: Control Functionality
Superharness User Manual Rev P3 3 Control Functionality Figure 4: Single throttle output voltage of Superharness controls both power and regenerative braking in Phaserunner/Baserunner controllers. The Superharness is able to combine the signals coming in from throttle and ebrake devices into a single voltage output to the motor controller. That output signal floats at 0.95V, increasing to 3.6V for maximum power, and decreasing to 0.0V for maximum regenerative braking. -
Page 7: Bidirectional Throttle
Superharness User Manual Rev P3 When the throttle is activated, the green LED will change in brightness from a low dim colour to full intensity allowing you to verify correct throttle operation. 3.2 Bidirectional Throttle The bidirectional throttles (sometimes called wig-wag throttles) also plug into the yellow 3pin Higo plug. -
Page 8: Analog Ebrake Control
Superharness User Manual Rev P3 Figure 7: Most Ebrakes are switches that connect the ebrake signal line to ground when the brake lever is pressed. Pinout shown is from male connector perspective. The red LED will illuminate at full brightness whenever the digital ebrake is pressed, and the output behaviour can be customized (see section 7.4). -
Page 9: Display Options
Superharness User Manual Rev P3 Figure 9: The analog brake lever has the same 1V - 4V nominal ouput as a throttle. The Superharness remaps this into a 0.8V - 0.0V regen command. We recommend having just one analog brake lever hooked up to the harness. -
Page 10: Dc Light Ports
Superharness User Manual Rev P3 know what communication protocol is programmed on a given device and Grin cannot offer any assistance for hooking up and troubleshooting other displays beyond what is documented in this manual. Our system prominently features regenerative braking which results in negative current and negative wattage on the display, and our displays have been customized to handle signed values and show this properly. -
Page 11: Rear Port
Superharness User Manual Rev P3 5.2 Rear Port The rear DC power port can be setup in one of five possible modes depending on the desired behavior 1. Always On: Power to the rear light port is activated whenever the Superharness is turned on. -
Page 12: Installation
Superharness User Manual Rev P3 6 Installation The Superharness is designed to mount beside the stem of the bicycle with the LEDs visible to the user. A tilting mounting bracket is supplied to secure it in place with two cable ties. The 9 pin cable runs backwards on the downtube to the Baserunner or Phaserunners motor controller, while the signal cables face forward in front of the handelbar. -
Page 13: Setup And Configuration Mode
Superharness User Manual Rev P3 7 Setup and Configuration Mode The behavior of the front light port, rear port and the digital brake input can be customized via a setup process that uses the brake lever as a button. Entering Setup Mode Power on the device while the ebrake lever is depressed to access the setup mode. -

Page 15: Running Without A Throttle
Superharness User Manual Rev P3 8.2 Running Without a Throttle Grin always recommends having a throttle on the ebike even if the primary control mode is with a PAS or Torque sensor. There is no downside to having a throttle available and it can be an invaluable backup if there are ever problems with the pedal sensor or drivertrain. -

Superharness User Manual Rev P3 8.5 LED Fault Codes The embedded red, yellow and green LEDs do not need to be seen in normal operation but they provide useful feedback about the state of the Superharness and associated peripherals for setup and troubleshooting. These are discussed in section 3 Control Functionality and summarized in the table below Table 1: LED Control Mode... -
