The low pressure side.

High side, If you charge liquid on the low side it can cause the valves of the compressor to break.
yes
Yes, in order for the compressor to take on the new coolant and oil charge the compressor ideally should be running. It is posiible to begin charging the system with freon prior to compressor initiation, however to get an accurate reading of the pressure in the system the compressor should be cycling with differential valve operating properly. If it is clogged or the compressor is not cycling then then low side reading will give an elevated pressure while charging the system. Does that make sense?
You should just let the system take the refrigerant out of the can by itself. It is not good to force liquid r134a into the low pressure side of the ac. The suction of the compressor will draw the r134 out by itself and stabilize the system as it goes, it may just take longer than you want.
The Low side line attaches to the compressor on the driver side of compressor. The charging port faced forward. The high pressure port faces up.
You can find the air conditioning low pressure charging port on top of the air conditioning compressor. The low pressure port will be on the right hand side of the air conditioning compressor.
there is a high side charging port up top and a low side underneath the car on the compressor.
the compressor should be under the hood on the front passenger side, it should be.
The larger line is suction. The larger line is the suction side which should be on the right side of the compressor......
The King valve is closed, starving the low pressure side, creating more vacuum while charging with a liquid
