Its important to have the system to be completely evacuated and have all the tools youl need ready before you start like guages manifold vacume pump hoses refrigerent and so on .if you havent done it before it might be a good idea to just have a ac specialist do it for you ..but if you decide to do it yourself youl still need to bring it in for a complete evacuation of any old oil and refrigerant or moisture via a vacum pump for recycling before you get started most shops will do it for you for cheap or free of charge ..but as for the refill coupler its in the engine bay theres 2 a high pressure line [skinny)and a low pressure line the low pressure line is (the bigger one )thats the one you fill it at .. when your ready to start let us know .. good luck
