| For the "drive by wire" cars, the panel and cable set is all the is required.
I believe you have an E46 with a throttle cable. That makes things much more complicated. BMW doesn't sell a retrofit kit for that engine and I haven't heard of anyone successfully adding a factory BMW cruise control.
This is what realoem says "Cannot be retrofitted, since vehicle is not equipped with wiring and various control units necessary."
At a minimum you will need the control unit and the cable actuator. There may be some other hardware needed such as a switch for the clutch pedal. Figuring out all the wiring is another story.
I found the diagram with all the parts of the cruise. At least I think this is for your car:
... and this is the picture of the retrofit ...
The "empty box".
