Easy. find the compressor. The larger hose attaching to the compressor is the "suction" side. This is where you install the refrigerant.
The smaller hose, whether rubber or metal as it travels to the passenger compartment, is the high pressure side.
After installing refrigerant and as the compressor is running, the larger hose will feel cool and the pressure side will feel hot.

Your service port will always be in the larger line of the two .. which is low pressure side. It might be in the dryer also which is low side.. your dryer is about 3 inches across and 8 inches long and also has your pressure switch for the AC compressor in it.. holler if you dont find it now... thanks Jerry

The low side service port for your air conditioning system is located
on the top of your A/C accumulator (can). It is located on the passenger
side of the engine not too far from your heater fan motor. It has a plastic
cap covering the valve.
