Low pressure Service fitting on a CGT?

[David.Ullrich at ferguson.com]

As you know I had my system converted to R134a. I want to check the pressures, as I have a feeling it might be overfilled and  also want to add some Quickboost. Where is the low pressure service port? Is it the one that's in front on the passenger side close to the compressor or the one in front on the drivers side coming off near the receiver/dryer? TIA!
