If you are doing this to a s4 car and you have to ask you are in big trouble.You have to keep everything together,S4 ECU,S4 HARNESS,S4 FLOW METER,S4 MAP and S4 INJECTORS(there is a way to use S5 injectors on S4 cars and viceversa)

Now if you have a S5 NA you need to source everything above posted(of course s5 versions of it)and plug everything in using your stock na wiring and your golden.
