Inline hidden wire brake sensors

[Matt500]

Hi, hopefully, someone can advise me about fitting an inline hidden wire brake sensor. I'm installing an e-bike kit for the first time. It comprises a 250w front hub motor and controller model KT36ZWSR-XFCF06. The wire harness from my controller to the KT LCD5 display includes the display connector, two x 2-pin red female connectors and 1 x 3-pin orange female connector. I understand that the 2-pin red connectors are for brake sensors, and the 3-pin orange connector is for a throttle. I have no need for a throttle. I want to fit an inline hidden wire brake sensor (HWBS). From what I can tell, HWBS all tend to have 3 pins and don't, therefore, fit the 2-pin red connectors. I wonder if I can use the orange 3-pin throttle connector for the HWBS.

I have a front hub 250w bike with KT controller and I have not fitted in line brakes to it as the motor power stops as soon as I stop pedalling, so IHMO I'd say that you don't need the brake UNLESS riding fixed wheel.

I am guessing that a three wire HWBS sensor has power, ground, and the brake signal. If you give it +5V volt, the signal can usually be fed to the two wire red connector, as long as you keep ground, You cannot put the HWBS direct to the throttle.

Sort of. You can cut off the 3 pin throttle connector since you don’t need it, and one of the 2 pin brake connectors. Then graft the 3 pin to the severed 2 pin cable for the gnd and signal wire, and use the 5v from the severed throttle cable to add the 5v required by the cutoff switch. No additional parts required, just some solder and shrink wrap.
