The low side service port is usually located between the AC compressor and evaporator. The low side service port will have a black or blue plastic cap that needs to be removed.

What happens if you put Freon in the wrong port?

If you hook up to the wrong port the compressor can push refrigerant into the R134a canister under high enough pressure to cause it to burst. You always need to connect the canister to the LOW side. This way the compressor draws in the refrigerant. Refrigerant can spray out if the fitting is not connected properly.

Actual readings will vary according to ambient temperature. The low-side should be near 30 PSI at 90 degrees Fahrenheit or less. Pressure that is too much lower or higher shows there is a problem. On a properly working system, high-side pressure will be about twice the ambient temperature, plus 50 PSI.
