Yaris third gen manual to automatic climatecontrols

[yaris|||]

I have a third gen yaris with factory manual climte controls.
I know that this version was offered with optional automatic climate controls that you can esely find on ebay and fit perfectly with sensors already integrated.
I'm wondering if I can swap the manual controls with the automatic ones without rewireing the whole dash and just swap the two units.

besically the short question is: Are the motors that change where the air is blowing included with the automatic unit or you have to take apart the dash to put new motors and aditional wireing?
