Yes, it probably would.

If you MUST hook it up to the fluorescent ballast, then you have to hook it up to the black and white wires. This is assuming that these are the power supply wires (i.e., the plug in part). You can't run the fan "off" the ballasts. You can share the plug, but that's it. Personally I think it's better not to share plugs though, because you never know when you need to replace one thing and you don't want to affect other things while you're at it.
