Main9 Quad Controller Splitter

This cable connects a single Main9 Harness or Main9 harness to three or four motor controllers, allowing you to make a 3WD or 4WD  ebike with a single display and throttle control. There is a primary controller identified by a coloured band of red shrink tubing, and three secondary controller hookups.  Two important things to note about this splitter:

• PAS control:  The torque or PAS sensor needs to be plugged into the primary controller, and only the primary motor will be powered when operating under pedal control.
• Display Power: The display only communicates with the primary controller as well. This means that the watts shown on the display represents just the power draw of the primary motor, not the combined output of both motors.

When using throttle and regen braking, all 4 controllers see the same control signal from the Main9 Harness and operate accordingly.
