Many of the cables do not go far and thus you should be able to trace
TV's Tune TV's to channel 3.0 Touch the center wire with finger.. You will know when you find the right wire.

Harbor Freight has,I'm told, a cable sorter,, You hook the colored "end cap" on the cable, then hook the cable to the tester which says "Red Cable" or "Blue Cable" and it's that simple. A toner is useful too, Hook the transmitter on one end adn the one that splits your ears is the other end of the same cable.
