Looking for the low pressure side on AC system

I'm about to add more refrigerant to my AC system, but I don't know where the low pressure side is (3800-II engine). Is it the port by the accumulator?

I dont have a 3.8, but the low side port is usually located near the accumulator. Sometimes it has a blue cap, and the high side has a red cap.
