You need the S5 harness and sensors.

the s5 OMP is electric where as the s4 is mechanical, and you can't just swap them out because they have different bolt patterns.

s4-s5 swaps are a pain in da asss. :us4allswi woowee 15 more hp

is this a turbo or N/A swap?

I have the same problem...but i have a s4 motor s5 fuelinjection/Harness...I was thinking about just buying a fuel injection controller and run everything off that.
