Re: Where is low pressure connector located on the
The compressor is located under the drivers side of the engine and in front of the tire, you have to remove a protective plate to get at the low pressure switch. It is possible to reach this without jacking the car up, but it would probably be easier if you do.

Todd, Low side A/C port, Check the attached links,instruction and guides, Good luck

There should be two lines/hoses that come from the compressor. If you can locate these lines, the low pressure side is the larger diameter line or hose. The high pressure side is the smaller diameter line/hose. The re-charge goes into the larger, low pressure side.
In order to charge, you must locate the low pressure valve to install the refrigerant. The low pressure valve is between the compressor and the evaporator. Do not charge on the High Pressure side, The high pressure valve is between the compressor and the condenser. To locate the low pressure valve, follow the line that comes from the compressor and routes toward the firewall. The valve will be somewhere on that line. Do not overcharge. The amount of pressure that is needed on the low pressure side will depend on the ambient outside temperature.
their are two ??one high and one low pressure connector and without the correct machine to re-gas do not attempt to touch anything as its extremely dangerous with high pressures and volatile gas that can freeeze a finger with frostbite in a second
Service Gauge Port Valves
The high-pressure service gauge port valve is located on the A/C receiver drier manifold and tube assembly.
The low pressure service gauge port valve is located on the manifold of the A/C compressor manifold and tube assembly at the A/C compressor.
A/C evaporator core
Thermostatic expansion valve
Manifold and tube assembly—thermostatic expansion valve
Manifold and tube assembly—A/C compressor
A/C charge port valve (low side)
A/C pressure relief valve
A/C pressure transducer
A/C condenser core
A/C charge port valve (high side)
Manifold and tube assembly—receiver drier
Sensor—evaporator air discharge temperature
The lincoln better idea engineers put the low side freon port in a peculiar place.. You will find the low pressure port near the compressor under the car on the driver's side. You will need to put your car on a lift to get to it. Once you raise your vehicle, take the plastic shields off and you will find the compressor...yup...it's a tight spot. Hope i was able to answer your question...be safe.
