If you need refrigerant that usually means you have a leak in the system---why not stop at South of the Border and have someone put a set of gauges on the car---then you will know what is really wrong
The low pessure is the large line, the top port. If you buy one of those cheapo adaptors, it will only fit the low side port, they are different size connections.
If it starts cold then gets warm, I doubt it's just low on refrigerant. There's probably something else going on. Would suggest taking it and having it actually checked out rather than just pumping freon into it, but if you're on a road trip I understand the situation there.

40f in NY. Don’t need the AC for now.
So this is the low pressure?
I hooked it up to STAR. I got a 1075B communication error with the AC. Perhaps a sensor.
will keep looking into it
