More than likely, all you need are the green and red wires. The black
and yellow wires would be used for a second line if you had one. In a
normal residential system, they are not used, even though they may be
hooked to terminals as if they are.

A telco will NEVER use the yellow and black lines for a second line with
a normal RJ-11 installation. Those are for lights and grounds in key
systems, etc..


A lot of the materials I've seen (including wiring diagrams for jacks)
say yellow/black is for a second line. Also, if you have a third pair,
blue/white for a third line.

I don't know about key systems, but aren't the lights (that use
yellow/black) obsolete?
