Yes, the smaller one would be the low side service port. Also, yes if the line is loosened between the two ports the orifice tube is there.
The low pressure port of the A/C system usually has a blue or black dust cap and is located either on the larger diameter metal tubing typically found between the evaporator and compressor, on the compressor itself, or on the receiver direr (orifice tube systems only). The high pressure service port is found either on the smaller diameter tubing or the compressor and is larger in diameter. Only charge through the low pressure port.
I have a 94 and mine was in the lower evaporator coil line actually in the coil at the firewall. It could also be in a fitting on the smaller line coming from your evap. coil.
the orifice tube is located in the smaller high pressure line or liquid line between the condenser and evaporator and if you look hard enough at metal portions of this line you will notice squares or flats that prevent the tube from being pushed in too deep

Its located on the accumulator which is near the firewall on the passengers side........
you have to change the orifice. propane operates under higher pressure than natural gas thus requiring a smaller orifice. call any place that sells and services gas appliances and i`m sure they can be of help.
On a 1996 Taurus, it's the smaller line located above the passenger fenderwell right below the low pressure line (hidden by the larger line). It has a foam wrap around the junction (2 nuts) that can be separated and the orifice tube removed.

exhaling causes negative pressure in the airways of the lung structure. the weakened muscular wall of the airway responds to this negative pressure by collapsing inward narrowing the airway. result is air flowing through a smaller orifice creating a wheezing sound.

In the inlet line on the evaporator core. It is the smaller one.
It should be the smaller high side line going towards the condenser near the radiator
