GenIII dbw cruise control is just a matter or having a couple of switches interface from the TCC/Brake switch and +12v, to the correct pins on the ECM. I have parts sitting in my garage to set mine up, its a pretty easy option actually.

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
