Is the wire Lite green, or Dark green? The lite green is the ground that makes the stator work. It MUST be grounded. you can extend it to any point on the frame, or better yet run it to the battery. It originally went to one of the mounting bolts for the electric starter. Use a ring terminal wherever you mount it. The dark green on the 2t models is the wire that controls the rpm limiter, and if in your case it has been cut, it should be continued to the cdi.. In either case you should be able to open the harness a little in the general area to find the continuing end to it.
