AC Lines Question

I've looked all morning for a picture that would show me what I'm looking for and haven't found it.


I have a 1990 Iroc and swapping in a 2000 LS1/T56 combo. My question is, which Air Conditioning line is the one that goes onto the large fitting, 3rd generation dryer? In the picture, my finger is pointing at it (3rd generation fitting/dryer). The other picture is the Ls1 compressor, it has one line that is bigger (thicker) than the other, with a longer hose. Does the thicker line go to the large 3rd generation dryer fitting?


I have an AC place that I took it to, they will replace the fittings to make it work but they weren't sure which line went where. I'm not sure either. I'm continuing to search, any help would be appreciated.


thank you

Re: AC Lines Question

The thicker line goes from the compressor to the 3rd gen dryer. Smaller lines goes from compressor to condenser.
