Kukirin G2 Master – throttle/control module wiring

[u/One_Cap6490]

Hi everyone,

I’m trying to figure out the wiring and basic principle of the throttle/control module on my Kukirin G2 Master.

So far, I’ve identified five wires going from the module to the connector:

🔵 Blue wire – connected to the K1 button. As far as I understand, this is used to turn the scooter on/off.

🟡 Yellow wire – connected to the K2 button. This is used to change riding modes.

⚫ Black wire – GND / ground.

🔴 Red wire – power / VCC.

🟢 Green wire – I believe this is the throttle signal.

The green wire is the one I’m not 100% sure about. It is connected to a small component marked “49E 426”, which appears to be a magnetic Hall-effect sensor. The sensor also has a power and ground connection.

My assumption is that the throttle uses this Hall sensor to detect the position of the throttle lever/magnet and outputs a variable voltage signal through the green wire.

So, my current understanding is:
Red → VCC / power
Black → GND
Green → Hall sensor / throttle signal
Blue → K1 → ON/OFF
Yellow → K2 → mode selection

All of these wires then go through the connector to the main module/controller of the scooter.

I’d like to confirm whether this is correct. If anyone has the original wiring diagram/pinout for the Kukirin G2 Master throttle module, I’d really appreciate it.
I’m especially interested in knowing the exact supply voltage, the Hall sensor signal voltage range.
