The big green connector is for the EEC power relay and is important. There is an always hot wire black/orange and an ignition controlled that activates and closes the EEC when you turn the ignition key.

The two wire gray connector with a black wire and light green with yellow strip is for courtesy lights, which may not be required in your setup.

I hope this helps you, good luck!
