Help with ls1 coil wiring on lt9c

1 Attachment(s)

I am trying 2 finish my LT9C install and i am a little confused with the coils.
One pin is 12v ignition
One pin is signal from LT9C ecu.
What about the other 2 pins?
The one is a ecu ground and the other one is earth ground according 2 the diagram...........do i need 2 ground the earth pin 2 the block somewhere?What about ecu ground?
