Hello, I'm Danny.

Sorry, your picture didn't come through. Can you resend? The low side access port on your A/C system will be covered-protected by a blue colored plastic cap. Get back to us with your picture and we'll go from there. Hope this helps and thanks for using 2CarPros.

I think the picture uploaded this time?
The caps are more greenish than blue, they are marked up, the larger diameter pipe has a large 'L' with 'DI' below and the smaller diameter pipe has large 'H' with 'DI' below. So I'm guessing that indicates Low and High pressure.
Cheers Paul,
Thank you for replying

Hello again.

Yes, the larger diameter line "L" is the low side port you will use to add refrigerant. Here is a tutorial show how to recharge your A/C system:
