Which is the low side a/c port on the 2001 Chevy Blazer

I see one on a thin pipe and one on top of the Accumulator and both have black caps with the same writing. There are no "L" or "H" makings that I can see. If needed I can sens a picture.

Low side port is on the accumulator and is smaller, high side is on the smaller line going between the evaporator and the condensor

With R-134a the fittings are different sized so you can't charge the high side with freon. They only fit one way.
