Mine has no connection either but I am not at all surprised to learn that newer systems do. It's probably a very inexpensive modification to have a pressure sensor changed from a binary good/bad to be calibrated and report the actual pressure. Temperature sensors before and after the evaporator coil could report delta temperatures. Ammeters and capacitance meters could be added to check current draw and the health of the capacitor.
