Wiring a Workhorse 7 ballast to a single 48" T5 fluores

[Andy]

Do I use one red and one yellow as in this diagram from the Fulham web site. http://www.fulham.com/NewFiles/wire15.gif
What do I do with the other wires. When I wire the black and white wires to a grounded extension cord does it matter what wire the black and white go to. On the extension cord, both non-ground wires are white.

Thanks again.
