Answer
Rickey,
If I recall correctly, your low side port is mounted directly to the manifold mounted to the compressor. If you look at the driver side of the compressor, you should see the cap for it, or the valve itself.
If for some reason it is not there, simply trace your larger line coming from the compressor and it should be mounted directly to it.
