I want to wire up a new phone jack, but I took the old one off before I
remembered the wire positions. The old one was working fine, it was just
ugly.

The phone wire from the wall has 3 colors blue/yellow/white

The phone jack has 4 wires black/yellow/red/green

Any idea how to hook it up?

The house was built in 1958, it is in Canada, if that matters at all.

Thx
Roland

Roland you only need to of the wires in order to have service at that jack
so, hook yellow to yellow and black to blue, this should work because it
sounds like you have CAT 3 cable running through your house with with a
newer version of a rj-11 connector. but I may be wrong you could always go
to the CSA (Canadian Standards Association) website and find the correct way
to terminate that jack! I hope this helps

black to blue

Residential phone wiring in North America used to use
four colors, red/green have always been "line 1" and
yellow and black for other purposes (e.g., for "line 2").
If your replacement phone jack has red, yellow, green,
and black wires, and you have a single-line telephone,
then you want to hook up the red and green wires.

Newer phone wiring uses pairs of wires that are twisted
together, and a standard color code that assigns colors
to pair numbers:

Residential phone wiring of this type usually will have
three or four pairs with the colors being blue/white,
orange/white, green/white, and maybe brown/white. The
blue/white pair is supposed to be "line 1", but if it
was not installed by a professional, then your phone
line could be on one of the other pairs instead.

There is ~50Vdc between 2 wires; those are the line (red/green).
If someone calls you while you are messing with the wires,
there will be ~100Vac on them.

A third wire may show continuity to ground
(water pipe / 3rd prong in outlet); that is ground (black).

Or you could go to the newsgroup com.dcom.cabling and get some advice
from people who know what they're talking about.
