Greetings electrical gurus!

I would appreciate some assistance:

I am upgrading a 4 four foot T12 bulb 2 magnetic ballast fixture to contain T8 bulbs and new electronic ballasts. In the fixture, one ballast powered the inner two bulbs and the other the outer two bulbs.

Problem:

I brought the ballasts home tonight and found they lack all the wires my old ballasts had.

These are Sylvania Quicktronic QTP 2X32T8/UNV ISN-SC ballasts.

They have on one end a red and a white wire, and on the other, two blue wires.

How do I wire the two ballasts to power the sockets? I have the usual one white and one black power wires entering the ceiling fixture.

I would sure appreciate some guidance.

Thanks!
