Telephone Wiring Diagrams and Connections
- The disconnected wires are three white and one blue one.
- I have one blue wire, one attached to a terminal, and I attached the loose blue wire one to it with no result.
- I have four terminals with one attached to each, colors, red wire, blue wire, black wire, and green wire.
- Should a white one be attached to each terminal?
- Or should one white one be attached to another white one, or what do I need to do to able to make out going calls?
