s4 drivetrain into s5 chassis

Will it physically fit? Absolutely.
Will it be plug and play electrically? Hell no.
You would want to strip the S4 engine down to the block and use an S5 front cover, electric OMP, ECU, MAP sensor, AFM, TPS, TB, and probably go ahead and use S5 manifolds as well.
Trying to get an S4 engine management harness & ECU to work with the S5 body harnesses will not be fun. It can be done, but it's a lot of work, and can lead to some serious problems if mistakes are made.

Note that I said body harnesses. That means the front harness, the engine harness and the rear harness. The front harness in particular wraps around half of the car.
Keep all electronics and wiring harnesses the same series.
