Finding ports to convert from r12 to 134
SOURCE: trying to locate my low
Wow! What a helpful site! Fifty people asking where the low pressure port on the a/c is, not one answer! a simple diagram would suffice! Its not like we're asking what if my car makes a punkata punkata noise, where the hell is the damn port? a picture, drawing, general location... screw it im gonna put it on the high pressure side(clearly visible) and then sue g.m. when it blows in my face, like their mom

red is high
green is low
you can charge the low side until
the large line is almost cold enough to frost at the accumulater

Look near the radiator and find the 2 aluminum lines running from the condenser. If you trace those lines you will find a fitting on each of them. There should be a cap on them one says H or high and the other L or low. One is the high pressure line and the other is the low pressure line. Please be careful fooling with the AC system can be very dangerous to you and your car. The last thing you want is a face full of prion. Or to blow up your AC system because you over charged it. Good luck.

The easiest way to locate the low side charge port on any vehicle is to locate the A/C compressor, follow the "larger" of the two lines all the way back to the firewall. Some where along that line you will find the low side charge port.
Good luck.
