Bought a Steelmate S881 motorcycle alarm from Tao Bao, and watch the video tutorial for the installation.
There are total 8 wires
Red - Connect to Ignition switch input
Orange - Connect to Ignition switch output
Blue - Connect to the Starter switch output (remote start)
Black - Connect to Battery negative terminal
Yellow - Connect to Left signal
Yellow - Connect to Right signal
Grey - Connect to crank shaft sensor (immobilizer)
Pink - No need to connect for （直流车电火）
I am puzzle how the grey wire connect to the crank shaft sensor immobilize the vehicle? Any expert to advice?
