Please don't tell me you're using those godawful plastic things that snap on to wires that cheap alarm fitters use, this could be the reason if they haven't made a proper connection, though usually they go the other way and all but snap the wire.
Easiest thing to do with jobs like this is to chop the connector off the old clocks and wire up everything to it in the same places, also means you have a single connector if you have to remove the new clocks again.
