hey bud, just put the black to black which is your power...put the white wire to the blue, this is your neutral which basically brings the unused amps back to the panel, and the green gets screwed down in the middle of the two, this is your ground, it protects it incase something goes wrong. your fixture should have came with a screw of somesort, if not just use anything untill you can get to the store and buy a ground screw...there like a chrome green anidized color...good luck on your grown
