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?
 
Hello Latec,
You're just lucky if the connector is the the same but every company decides itself how they plug their wires into the connector.. So no, they aren't all the same and you should measure with a multi-meter or change the wires until it works. With a very thin screwdriver its possible to change the pins position, but you can also cut and solder the wires together.
