All the threads I read about these only have 2 wires. I pulled this one out of a Arch Rivals and it has a molex with: Black, White, Green and Blue.

What are the blue and green wires for?

Thanks in advance.
 
post a pic. If you have 4 wires TO the light fixture, then that's weird. if you have 4 wires ON the light fixture then that's to be expected....

You sure the wires do not just run through it to something else... Example is vanguard fixture also has the power wires runing throught the fixture to the on/off switch..

Should have two wires only unless there is a ground wire then 3.

New electronic ballasts have 4 wires (and sometimes more), but your wire colors don't suggest that you have one...
 
Post pictures of everything so we can trace the wires.

Standard wiring colors are:
Black = Mains HOT
White = Mains NEUTRAL

Green = Mains Ground

Brown = Post-Switch HOT (e.g. actually feeding the circuit if the switch is on)
Blue = Post-Switch NEUTRAL

The Brown/Blue mapping is the common colors seen on on AT (not ATX) power supplies with the hard switch external to the supply, or as colors in some standard computer power cables if cut open. It's an IEC standard that most of Europe follows.
 
Ah ha! You have a ballast for 50 or 60 hz operation. Here's how you connect power:

For 60 hz operation (in the USA):
White: AC neutral
Black: AC hot
Green: frame ground
Blue: not used in this application

For 50 hz operation (other countries):
Blue: AC neutral
Black: AC hot
Green: frame ground
White: not used in this application
