Where is the low pressure side of a 93 Dodge Shadow AC system?

On a 1993 Dodge Shadow's AC system, the low-pressure side is located at the smaller diameter AC line. You'll typically find the low-pressure port (where you'd connect gauges for charging or checking pressure) on this line near the compressor. It's usually a smaller diameter than the high-pressure line and may be made of aluminum. The low-pressure port will usually have a blue cap.
