Here's some pics to give people an idea of where the IACV is.
The red squares are the IACV unit and the yellow squares are the bolts (sometimes you can't see the actual bolt), but there are two on each side (one high and one low).
*Note the multi-tap power connector. If you are going to fully remove it, that must be removed too.
*Make sure you take a picture of the IACV top plug of the angle and also the screw positions. You'll notice they are marked from the factory with white to give you an idea of where the screws are supposed to be. Adjusting the angle of the top plug on the IACV and the screws is said to adjust idle, so make sure you take pictures so you know how to line them up and how deep the screws are. Failing that, you could just adjust things until your idle is where it should be.
*There are 3 hoses going into it, 2 coolant lines on each side and the clamps can be released by squeezing them together with a wrench.
*The large one at the back I haven't removed so I'm not sure what it is for.....I'm guessing the obvious, air
