Look at the high pressure AC line just before it enters the HVAC enclosure under the hood next to the firewall... You can usually actually see the divots in the line where the orifice is staked in place to my memory.... The high side line or the hot line is the one coming from the condensor to the HVAC case.... Teh high side line gets real cold real quick across the orifice.... The low side line is the cold one that goes from the HVAC case to the accumulator.
