Question about 1992 Lexus Es 300
A/C low side ports are located on the 'thicker' plumbing vs. the 'thinner' plumbing coming off of the compressor.
Just follow the low side pipes from the compressor to the first low side port. It should also fit a quick connector onthe hose/can combination for r134a. The high pressure side port will not work with the low side hose quick connector.
Hope this helps.

This is a little A/C 101. Follow the A/C lines. All A/C systems have a high pressure side and a low pressure side. The high pressure side is from the compressor to the condenser coil on the front of the vehicle to the evaporator coil in the dash. At the expansion valve in the evaporator the pressure drops. At the expansion valve the refrigerant changes from a liquid to a gas. This provides the cooling. The low pressure side is from the evaporator back to the compressor. Usually the high pressure lines are smaller than the low pressure (suction) lines.
