Hi, I do not see that your question has been answered, so I will answer it since I also have a 2004 superduty.

You add a/c gas to the low pressure port between the passenger side battery and the radiator. It has a black cap, and your a/c equipment should have the right fitting to attach to this no problem. Good luck!
