Things are starting to become clearer.
Into the backing boxes of each of the sockets, except the end of the daisy-chain, you have two grey cables?
Before you removed the orange wires, every socket had a pair of orange wires connected, except for the end of the daisy-chain (identified above) and the first socket (which should really be an NTE5A). Can you remember which socket is the latter? Please identify it by the explicit URL to its picture.
Once you have your IDC insertion tool, go to that socket and remove one pair of wires (2 & 5) from one of the grey cables. It is a 1:1 chance that you have disconnected the "extension" wiring. Plug a phone into that socket. Does the phone work?
If yes, label the grey cable with the still-connected pair as "incoming BT Pair" and the disconnected grey cable as "Extensions".
If no, then disconnect the currently attached grey cable and re-attach the pair from the previously disconnected cable.
Re-check with a phone. And then label the cables appropriately.
The report back.
