Ok so i've seen that the NA S5 and S5 Turbo II harness are nearly indentical except for 2 wires the Turbo Duty Soleniod rewired from the 6 port induction soleniod and the Knock Sensor which is the NA motor doesn't have but has a harness for,

i just wanted someone to confirm that my info is right or someone show a ecu pinout so i can check myself thanks

 

ECU pinouts are in the FREE FSM that is available in the FAQ thread on this site. Download the FUEL AND EMISSIONS section and look in there at the subseciton called CONTROL UNIT.

 

Its also some wiring for the power steering, but thats as much as I know since I don't have power steering.

 

its three wires IIRC
