If the TB, TAC, Pedal and ECU arent' from the same year/vehicle, then you need to make sure they are as close as possible. Different years used different calibrations for the pedal sensors, and certain models didn't use the TAC (even though the plug on the harness might still fit, it won't be setup correctly.)

Using components too different will result in a "DBW Mismatch" error, which can show itself a handful of different ways. Anything from lack of pedal response, to no control of the pedal whatsoever.
