Mexican Yaris get a different ECM than US and Canadian ones, so you would definitely have to test it to see. The place to start is to measure the voltage on the ECM pin 40, with the ignition in the on position. If you see 12 Volts on that pin, then there's a good chance that it will work.

If you shine a flashlight around on your instrument cluster, do you see the two icons for cruise control?
