So this is the choice cord.Its gots a black,white,and blue green wires.The only thing is the wires are thicker than the wires on the ballast.Is that a problem?If theres not a problem with that.The next thing I do is attach both white wires from the ballast to themselves,then to the white wire from the cord .I do the same to both black wires form the ballast,and attach them to the black wire from the cord.Right?And the green I spin it around the screw ,and tighten.Right?Also any reasn why,one ballast has those plastic orange things attached,and the other ballast does'nt?Is that normal,for a 6 tube 4ft. fluorescent?
