Are you editing the families and placing connectors (which are only available in the family editor) or placing “empty geometry” face based electrical devices within the project environment? if you are doing the former (family editing) I am not sure if Dynamo will help you much at this point. But if you are placing hosted “connector families” in the project environment, then yes, Dynamo can do that. You may not find many examples on here of that though. If you read between the lines though, there are many similar examples on the forum (placing baseplates on the bottom of columns, placing lights in ceilings, placing furniture on floors, placing doors in walls, etc). Just think of it generically as placing a hosted thing on a host, not placing a connector on a mech unit.
