the relay is just to give constant power to the coils. all the coils will get power from the same relay. each coil ground wire will trigger 2 coils wired parellel to it. since all the trigger wire does is cut off degrounds the coils and changes current path. liek warmonger said the only advantage would be eliminating the plug wires. would that be worth all the effort and money spent. i heard the stock coil in our cars are pretty good. im down for just gettgn a set of realy good plug wires.
