    The low-pressure service port (smaller of the two ports) is on the line that goes from the firewall to the compressor. There should be a blue or black ( not sure about green ) threaded cap on it. Just unscrew the cap and you're ready to add refrigerant. Try the 'How-To-Guides' feature on the AutoMD website for more specific detail to recharge the a/c system.
