The charge port (Low Side) is located on the low side line (Larger of the two) near the firewall of the vehicle. Sometimes it is even directly on the receiver/dryer, which is the large cylinder the large lines attach to.There will be plastic caps over the service ports that look like tire valve stem caps. Sorry, none of the manuals show the actual picture , just a description.
See the guide below on how to charge the A/C, it may help you find what you are looking for
