As written in title, on my, "Duh" ebike "brushless motor controller", on the "printed circuit board" everything motor, throttle, brakes, ect... has a designation, a location and a voltage . I've got good idea where it's supposed go but not 100% sure. I try not to make connections unless I'm 100 % sure voltage and or sensor won't blow each other up , agin any idea what the abbreviation (s) do they use for cadence sensor and maybe torque sensor ,
