I live in a 110 year old house. I followed the phone line to inside the house where there are a tone of different phone wires. I remode the kitchen a year ago and rememeber a line in the basement but its only a 3 wire line. No color lines just 3 lines twist together. If I want to turn this into an up to date phone line how do I connect the red and green wire to a unknown color wires?
