When the 2010's came out with it in the US this year (other markets had it earlier than us), I did a quick writeup. You simply wire a switch to bring the input to ground and press and release to turn VSC off, or press and hold to turn TRAC off.

It looks like the wiring is only there if the switch is an option (or standard) for your market. Also, for the US (where the switch is not an option), the instrument cluster does not have the VSC OFF or TRAC OFF lights.

This sounds promising. I bet the TRC/VSC in new Yaris is taken from earlier TS models.

But how on earth should I reach that A30 connector from engine bay. I have no place to go to take a look from underneath.
By that picture you provided, I'm not sure it's even visible without taking at least the battery out.

It's definitely not an easy place to get to. And, unfortunately, the only place it routes through is one of the connectors at the top of the dash, which would require removing the dash to get to. I have a feeling that you will find that the pin on connector A30 is empty on cars that don't have the switch. So, you would need to add the pin (Toyota Part Number: 82998-24250)
