Current layout of light in ceiling: 2 Light tubes 1 T12 Ballast Wiring: 2 Yellow 1 Black 1 White 2 Blue 2 Red 2 Yellow are on one end; black/white midway; 2 blue and 2 red on other end, 1 blue and 1 red going to each side of end. New T8 Ballast: 1 Black 1 White other end has 2 Blue and 1 Red. Power is off, my main question is how to wire the new ballast as their are more wires in the existing setup. Tried looking for a video online with no luck. The diagram on the new unit does not show any yellow wires in the diagram and shows one red not 2 red that are on the existing ballast. Hope this is clear enough as I am stumped as to what to do for the connection. Black to black and white to white is easy enough. Thanks all.
