I have an S4 TII parts car to pull from...What all would i need to take out of it (excluding motor, tranny, driveshaft, differential, axles, and brakes) to make it run in an S5 NA shell? I know ill need the ECU..but what wiring do I have to bring with from the TII?

 

kevin has a nice writeup with parts list :
