T8 Ballast Wiring - Help Needed!


Hello folks,

My fixture has 2 T8 lamps. The fixture and the existing 2-lamp ballast has 4 ports: one pair of blue wires, one pair of red wires, a port with a white wire and a black wire, and a port with blue, red, and yellow wires.

The replacement 2-lamp T8 ballast I bought from Home Depot only has 2 ports: one with a white wire and a black wire, and the other port with two blue wires and one red wire.

I am very confused on how this is supposed to work. My fixture has more wires than my new ballast (and even an extra color).

Your help will be greatly appreciated!

T8 Ballast Wiring - Help Needed!


I hope you did not take apart the old ballast without writing down where all its wires were connected.

Is there any diagram or instructions with the new ballast?

I didn't take down the old ballast yet.

There is a schematic but it makes no mention on what to do with what would be my fixture's resulting extra yellow, blue, and two red wires. The new ballast is a GE Proline T8. Model number is GE232-120RES-DIY. If you scroll to the middle of the page you'll see the schematic which you can enlarge:

And here is my original ballast (note there are more wires, including a yellow wire):

Some folks on another site were able to walk me through the solution and I got it working. In case anyone ever has a similar problem:
