Not sure, I'm not familiar with the 2k2. They were more prevalent with the older gasers sold in the US, rare in Europe. The 2k3 lighting runs off the yellow wire that grounds to the frame. There is also a white wire from the lighting coils, which is not normally used. Everything else goes to the ignition. I think the regulator would go on the same tab as the spark plug coil, it does on the later bikes.
A wiring diagram for 2k2 lighting would be helpful (some ktms, huskies and tms will also have used the same set up, if you can't find a GG one)
Maybe someone with experience of the 2k2 bikes will chime in.
