Wyvern,
Sorry for sidetracking your "wanted" post, definitely some good information here though.
In concerns to your original post... are you changing from pre-facelift to facelift climate control or trying to change to one of the auto control units? The reason I ask is because the heater assembly should be the same for all trim levels of the same year range, and mostly the wiring as well. As far as I'm understanding it, it's the control unit and sensors that make up the only difference (please correct me if I'm wrong Hikaru).
If you're converting from pre-facelift to facelift then there's more needed. There's also a lot of information available concerning that swap, to which I could provide links if needed.
