I would have thought it would be easier than it is, I can't find an illustration that shows it. I am even looking in GM service info. Where is the low side, I would guess on or near the accumulator. What I would recommend is you trace the discharge line from the compressor, to the condenser, and from the condenser to the evaporator. It should be within that area.
