Need to recharge AC. Found 2 High side AC ports. Can't find the LOW SIDE AC port. Where is is?

 

One of the two "high side" ports is the low side port. It should be the one that is closest to the accumulator. The orifice tube is located between the 2 ports. If you look closely enough, you will see that the two pressure ports are different sizes.

 

Didn't know the orfice tube was between the 2 ports. Hooked up my AC gauge set and added refrigerant. Now it cool inside. thanks for the comment.
