The first year the ETCS appeared was 2001, but it is apparently very rare. Seems it's only Limited. It might also be a Taco vs. 4Runner thing, a lot of things show up in the 4Runner that are either rare or nonexistent in pickups. I think by 2004 all 3.4L engines had it, though. You are 100% correct, there is no question with or without, the throttle bodies, the accelerator cable, etc. are different.
