SOURCE: low side service port
Hi, All air-con systems have stardard size air-con pipe connections.1 small 1large so you can`t connect to the wrong side,the connector usually has a ring you have to pull back to then push onto the pipe connection that when connected keeps the connection tight ,to disconnect it is the reverse of fitting BE carefully and do not connect or disconnect with engine running wear goggles and gloves and do not breath any escaped gas,if your not confident give it to an expert !!.

Your service port will always be in the larger line of the two .. which is low pressure side. It might be in the dryer also which is low side.. your dryer is about 3 inches across and 8 inches long and also has your pressure switch for the AC compressor in it.. holler if you dont find it now... thanks Jerry
