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

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 !!.

This job requires special tools and special training. If you lack either, you risk SERIOUS personal injury. Injury comes VERY EASILY!
You need to address oil levels, proper and legal refrigerant recovery, system evacuation, and recharge.
You were planning to also replace the receiver/dryer, correct? It also needs the oil in it measured and incorporated into the amount of oil (in %) that would need to be added. FAILURE to address these and other issues will guarantee premature system failure and likely compressor damage.
Take this job to a qualified shop.
