I guess the quesion is, are the clocksprings different for cars that don't have SW buttons from the factory as compared to ones that do?

The clockspring is different, as the wires go through it and the stock Yaris one only has wires for the airbag, horn and cruise control switch. If you forgo cruise control you can use those two wires to implement 2/3 of the steering wheel control functionality.

On pre-2012 Yaris for the US market there was not even an option of having steering wheel controls. Importing a European or Japanese clockspring was the only way of doing a vehicle specific upgrade.
