Recently I got a 354 wall phone that was miswired, and would not work. To rewire it, I dug up a diagram from TCI, but it was kind of hard to follow. I collaborated with Dennis a bit, then redrew the diagram (simpler) and took pictures of the internal components of the phone (to identify connection points). I have attached them here. In the wiring diagram, the Blue shows the parts inside the phone – ringer, dial, handset, etc – as well as the screw terminals within the phone. Wires are shown in Red.
Questions or corrections? PM me, or email at the address in my profile, and I'll take care of it.
