The low pressure charging port will be on the larger tube, usually near or on the accumulator. Follow the lines coming out of the compressor. One line will go to the condenser (in front of the radiator)[the high side] and the other line will go toward the evaporator (through the firewall) [this is the low side].

Here is a general diagram of an automotive A/C system.
