Many years ago, my father in law attached two track light rails to one ceiling fixture on a dimmer switch. It lasted until yesterday when I took it down. He had to split the two wires which were both white (having each two sides silver and copper) . The fixture I want to attach has one black , one white and one ground wire . I have put up ceiling fans and lights before . I am probably right about what I think I should do, but I got cold feet. How do I attach the new fixture to the two white split wires , both hanging from the ceiling as two Y's
