STOP right there!
You used the high side port. The connector off the compressor is
the high-side no matter what the cap color is.
The low side is between the condenser and the evaporator. The
smallest line in the system that runs from the firewall.
What bugs me is the connector should not have fit unless the
shop that did the mod buggered something up.

If it's a Sanden compressor, it can have the low side port on the
compressor, or even both low and high side ports on the compressor.
Also, the smaller of the two lines, is always the high pressure side.
The low pressure line is always the larger diameter line.

Good call, this makes a lot of sense. I'll give it another look
tomorrow. I'm pretty sure what I was attaching it to was a new fitting
though (from the retrofit).
