Hi Ken,
These electrodes are made to work with either electronic or piezo spark generators. The black wire has a round female connection and the white wire has a spade female connection. If you use it for an electronic generator, you would just push the round connector over the spade male on the generator. The metal is malleable enough to make it work. In this way, we can sell one part that fits both.
