Both off of 3vz's (fairly obious)

but what motor came with no idle up control on the TPS... notice the throtle body castings are diffrent also. (so its not like one is just missing it)

My plenum looks like the one on the left. I only have 3 vacuume lines going to the top of the TB like that, instead of 4 like the one on the right. My idle up control is on the opposite side of the TB, right below where the trottle cable hooks up. It looks a bit different though, it has a white plastic round section with "ARRAM" (or something like that--kinda hard to read the font) printed on it. I didn't notice any vacuume lines going to it either.
