I should probably know this, but....
I have one 4-wire phone line running from the main incoming phone connection
box to a standard phone jack. I want to add a second phone jack next to the
existing one for a second phone line, and I don't want to run a new wire.
So, here's what I am assuming:
1) Inside the existing phone jack, leave the red and green wires from phone
line connected to the red and green connectors inside the phone jack.
2) Then take the black and yellow wires from the phone line and connect them
to the red and green connectors inside the second phone jack for the second
I know what to do with the wires on the other end (at the incoming phone
But, is number 2 above correct?
If so, when matching the yellow and black wires to the red and green
connectors inside the phone jack, is it better or correct to connect the
yellow wire to the red terminal and the black wire to the green terminal?
Or should it be yellow to green and black to red?
