cep315,The two black and teal(bluish/green)wires connect to a branch circuit junction box in the basement, usually at a light fixture. What you need to do first is determine which wires are for the doorbell buttons and separate them into pairs. Also determine where those wires at the doorbell run to. You will need a ohmmeter or continuity tester to check those wires. Wherever you mount that transformer terminate all your wiring in that general area.

Post back when you have all your wiring straighten out.
