2004 Tundra should be completely electronic unlike the early "hybrid" throttle bodies (I say hybrid because they used a cable as a rough back-up, it was a stop gap to modern "fly by wire")
I need to amend my earlier statement because I was mistaken, the 2UZ-FE came only in 2 flavors in terms of throttle bodies. The early units came with the earlier semi-electronic throttle bodies and then later they were equipped with true completely electronic units. Both units operate by electronically operating the throttle blade, so there isn't any real way to convert them as far as I am aware.

Is there any chance your mistaking Singtoe's older throttle body design for a true cable driven one? I skimmed through his build thread and it looks like his powerplant is an older 2001 Sequoia 2UZ-FE which uses that funky hybrid design?
