I’m attempting to put together my first ebike and all is going well except I have ran into a snag. I have a ebike kit with a 750w bafang hub motor with the 850c display and the connector for the brake pin is yellow 3 pin connector. The hydraulic brakes are the tektro hd e350 with 3 pins and a yellow connector but don’t seem to be working. When I disconnect the tektro brakes and plug in a sensor that is meant to be taped to the brake and a little magnet it works and it’s also three pin and yellow. Aren’t all 3 pin brake cutoff sensors the same? If not what do I need to do to get the tektro brakes cutoff sensor to work?
