we just bought this house and want to put a phone in the
kitchen..unfortunatly, the wires are bare....now we bought the jack
and went to install it, and found that there are only three wires
coming out of the hole, red, green and yellow..no black,,,
how can we install this new jack to an old line that has only the
three colored wires?


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..


Wrong. It is quite common. Most recent time I ran across it was in this
very house, where the kid's bedrooms were wired with yellow and black to
the center conductors. Pre-cellphone era, Mama Bell heavily sold getting
a second line for the kids. Was also quite common with roommates sharing
a house (like at college) and wanting private lines to talk to their
sweeties, and to make sure there was no question about who pays LD
charges. (Back in school, I used to do a lot of moonlight phone wiring
for young ladies. Nothing illegal, mind you, just putting outlets where
they wanted them.)
