Re: Phase III Super/Spark CD system instructions
Blue wire to engine ground, such as a carburetor bolt they recommend.
It actually isn't a ground wire, it senses the voltage kick when spark jumps from the center electrode to the side electrode. If the blue wire is not properly connected, you loose 70% of the systems ability to sense engine needs.
