GenIV dbw is a bit more complex, which I assume is the one your referring to. It can still be done, but it isn't anywhere near as simple as the above method. The ECM needs to see function from the BCM for things like cruise control. There are some companies making retrofits for this, but again, no where near as straightforward as it is for GenIII
Actually it its, it just costs a little more......
