I see the spark on the good one. But is this just one lead to the power supply and do this.

just have the coil plugged in as normal .plug has 3 wires
middle is power to both coils the other 2 wires are the control trigger wires for each coil . control wires go to the ECU .. middle wires all connect together and then connect to 1 fuse ..below 2000 RPM both coil fire at the same time over 2000 RPM the ECU can fire coils 10 degrees apart
