on my chines 2 stroke 70cc engine there is not a green wire
The kill switch wires can be switched, all they do is complete a circuit.
:::::WIRING GUIDE :::::
Okay, first we will take note of our wires.
NOTE: Different brands tend to use different colors for some wires, so use the process of elimination to determine what color a wire is if it is not stated here.
*Kill Switch Wires : Green Wire & Red/Yellow Wire.
*Engine Wires : Blue Wire & Black Wire & White Wire.
*CDI Wires: Blue Wire & Black Wire.
*Other Stuff: Wire Cap
Now that you know what wires you have, it's time to connect them.
1. Engine's Blue Wire to CDI's Blue Wire.
2. Engine's Black Wire to CDI's Black Wire.
3. Kill Switch's Green Wire to Engine's & CDI's Black Wire.
4. Kill Switch's Red/Yellow Wire to Engine's & CDI's Blue Wire.
5. Engine's White Wire to Wire Cap.
