v50 ac port location
 

can someone tell me where are the low and high pressure ac ports located on a 2010 v50

Follow the low pressure suction line from the firewall back to the compressor and you will find it.

i see 2 lines a big one and a small one, which one to follow

The large line that gets cold is the low pressure line.

However, I'm concerned that you understand how to safely work on an air conditioning syste.

i just wasn't sure because i was watching some YouTube videos and most of the ac ports the caps were labeled L OR H, thanks so much for the information.
