I'm installing a dual jack junction box so that I can have two connections to the phone line. When I removed the old single box and notice the red, yellow, green, and black connector wires, I also notice that the main phone line had only 3 wires that were connected to the backing plate of the old single box. Well I desided to put on the dual box and fiddle around with the connections, but the phone that's in my bedroom is not working. The house I live in is over 20 yrs, and I think that is why there are only 3 wires coming into the house and connecting to the single junction box. So how is the connection gonna work for me with 3 wires in the house to the dual juction box and to the color wires? Send all info as much as possible.

Thank you,
Andrea A.

Each phone line uses only 2 wires. Newer houses are usually provided with 4 wires so you can have 2 different phone lines. Older houses sometimes have that 3rd wire but it's not required for operating a phone. (Somebody correct me, but I think it's just a ground.) It sounds like you have just one phone line, and want to attach an additional phone to it. You didn't say, but you probably have a red, green, and a black. All you need to do is continue to use the red and green and connect them to BOTH the connectors. The red will go on both the red and black, and the green will go on both the green and yellow. If you were using 2 different phone lines, the black and yellow pair would be for the 2nd line.
If your current wires have no colors, it's a little more tricky, buy you should be able to figure it out. One is odd and not really used. Of the two remaining, attach them to red and green and see if you get a dial tone. If not, reverse them. Then connect the red lug to the black, and the green lug to the yellow for the extra phone.

Thank you rpxlpx for the reply. In true detail, I do have 2 phone lines in the house. One of them (for the dual jack) that I'm working on is in the bedroom. You are right there are 3 blk lines coming into the house and by your sugestion I will work with it until I can get it to work. Again thanks for the info.

A little FYI. The polarity is unimportant when dealing with standard household phones.

Reference the comment from Rix Fix - actually, the polarity does matter if you're using Touch-Tone service. You can get dial tone if the wires are crossed (e.g., red to green and green to red). However, a Touch-Tone phone won't dial out...you'll continue to get a steady dial tone no matter what keys you press. If that happens - reverse the red and green wires and try it again.

Thank you Jim for the extra info. I did talk to a sales rep at Home Depot here in Memphis, and as much as he told me this project is mostly trial and error. So in truth I do have touch tone service for my house and I will work on this. Again thank you.
