The a/c ports may be under the air cleaner housing or under the car near the a/c compressor. Just follow the a/c lines until you find them.
The low side is passenger side near the firewall,,, the high side is on top near the radiator and condenser. if you look over and down diagnally you will see a colored cap (i thought it was blue, but i lost it,,,, so the high side is bigger and toward the front of the car
Cutlass and Cutlass Supreme may be different because mine is a '97 Cutlass Supreme SL 3.1 and the ports are under the back side of the air cleaner housing on the drivers side and the lowest port is the fill port.
