Hello! Just noticed no one has answered this. Welcome to the forum, I am not an AC mechanic but from past experience and some research this is what I find.
The low pressure side is down by the strut tower on the passengers side of the vehicle, the high pressure port is by the compressor. Now this is for a NON-Turbo charged engine; the specs for turbo charged set ups is different and is only listed in the factory service manual to which I do not have access. I am told that if you raise the cruiser, on proper jack stands or ramps of course, you can go under the car and find these locations by site.
Of course it is recommended that the system be evacuated and recovered, tested and then refilled with the proper weight of refrigerant.

Good luck.
