Where is the low side ac port on a 1998 sienna?

The low side port is on the left hand side when you are looking at the engine. You will see two aluminum and rubber lines. They have black plastic caps that pull off. The high side and low side have two physically different sizes. You cannot reverse the connections. The low side port is on the left hand side when you are looking at the engine.
