The individual coils each have medium gauge wires for power and ground, and light gauge wires for the signal when to dwell.
In original applications, were power wires to coils through a relay, so that power wires did not have power when ECU was not powered?
MSD boxes get wired direct to battery without a relay, and the signal wire I guess sort of acts like it's own relay.
