Fluorescent Ballast
The ballast in my 4 bulb T8 Fixture went bad and I need to replace it. The ballast has 3 wires coming out of one end (Yellow,black, white) and 8 wires on the other end (two blue, two red, two brown and two gray).
The replacement has only two wires on the one end (Black and white) and 6 wires on the other end.
How can you wire 8 wires to 11 wires?
Thanks for any help

There should be a wiring diagram on the ballast. If you post a picture we can help you decipher it.

I believe your 8 wires are black, white, 2 yellow, 2 red, 2 blue.
Your old ballast was just wired differently.
Follow this diagram if you are having trouble with the diagram on your ballast.

Each socket needs two wires coming out of it, one on the left and one on the right. Then the two wires from each needs to be tied with the corresponding ballast wire.
If you cut carefully, your ballast should have wires long enough to snip two socket wires off of each ballast wire.
