Ballast replacement: should the diagram be exactly the same as the old ballast?

Question

Everything in the old and new ballasts (for 2 40w fluorescent lights) lines up except the diagram for the new one shows the 2 blue wires above the 2 red ones. On the old one, the red ones are above the blue ones. Is that okay?

Answer 1

Yeah, it will work. Just make sure the power is off.

Answer 2

You'll be fine, follow the diagram on the new ballast.

Answer 3

Just match the blue and red on the tombstones where the bulb twists in and should be ok

red to red
blue to blue
