Yap, vamos bien parece, como a las 02:00am logre recopilar info que dice que al parecer, el "drive by wire" de estos motores tienen los "wires" entre la mariposa y su accionador, no en el pedal, con lo cual no es necesaria ninguna otra parte que venga en el auto.

Aqui unos extractos del tema en referencia:

“I wasn't planning on getting a vvti but in the end I got one and have never looked back. Out of all the cars I test drove, the vvti seemed to have the smoothest transition between the two turbos in sequential mode. Some people do not like the fly-by-wire throttle and the waste spark system (it only has 3 coils, so 3 cylinders have coil on plug and the other 3 have a lead from one of each of the coil packs to the plug)”
“Every supra had a cable pedal, including the drive by wire ones. the sender unit was located on the throttle body like a normal car but it was not connected to the throttle butterfly directly.”

“JZX110 1JZGTE VVTi is the motor I have and its drive by wire. It’s such a pain in the ass; i'm thinking of replacing the throttle body and intake manifold to switch to direct cable.”

“…fly wire throttle body that the VVTi engines have”

“Older Supras have a mechanical cable-operated throttle - there are no "wires" as such. The VVTi engines (and for that matter most newer Toyota engines) have a stepper motor controlling the throttle plate, with no mechanical connection at all to the go pedal - hence the term "drive by wire".
Having driven a couple of cars with drive by wire (including one Toyota, that weird semi-van thing whose name escapes me at the moment) I've decided it's a crap idea. I don't want some computer trying to second-guess my throttle inputs! A direct link between my foot and the throttle is what I'm used to, and it seems to work perfectly fine, so why change it?”
