Found this on jeep forum.com --There will be the low pressure port on the suction line, between the compressor and the expansion valve (located on the firewall). The high pressure port is on the discharge line, between the compressor and the condenser. Follow the line until you locate the ports. -- they talk about the low pressure port being right behind the compressor and the high one being by the shock tower. I trying to find you a picture
