Question about Phones
I am trying to install a new wall plate with a phone jack that the package describes as an RJ-25 phone jack. I need to connect the jack to the exsiting phone wire which has four wires: black, red, green, and yellow. The punch-down block diagram to connect the RJ-25 jack has eight connectors which the package diagram describes as: white/blue, blue, orange, white/orange, green, green/white, white/brown, and brown. Can you tell me if this can be done and, if so, which of the punch-down connectors should be attached to my four existing wires?

I found some good information on this site: http://www.ling.upenn.edu/~kurisuto/phone_wiring.html.
He lists that the old style wire has become obsolete, and shows a diagram of how they line up to the new style.

Take a look at this image:
Notice that the Line 1 will typically present on pins 3&4 and Line 2 on 2&5. I would think in your case Black/Blue is Line 1 (3&4) and Yellow/Black is Line 2 (2&5).
If you have a 1 line phone and only have 1 line active, then typically blue and blue/white can be connected to the Blue and Black of your Jack. If this doesn't work, switch with the Yellow and Black.
Please let me know if you have further questions. Good Luck!

Normally the conductors in phone cable are colored green, red, black and yellow in older style wiring. Green and red are used for a single line, and black and yellow are for a second line. Newer systems use wires that have conductors twisted together in pairs. White with a blue stripe paired with solid blue or blue with a white stripe is line 1. White with an orange stripe paired with solid orange or orange with a white stripe is line 2. (At least this is true in the US. You said "cheers" so maybe you're not in the US and the color coding's different.)
Chances are your line is using the blue and white wires.Residential telephone equipment isn't polarity sensitive so it really doesn't matter which wire you hook to L+ and L-. Try the white/blue combination first. If you don't get dialtone then try red/black. If still no luck you only have two more combinations to try.
Before you start with the wiring, take another phone on the line off the hook (if you have another one). This will prevent an incoming call from ringing the line, which can give a shock if you happen to be touching a bare end. The ringing voltage is much higher than the normal phone line voltage which won't bother you.
