from what i know it didn't get set-up for the car but he it is meant for the rx7 so i don't have to send it out to Australia to get re-flashed for it

4 injectors
1 coolant temp
1 air temp
leading coil
trailing coil
TPS

and that's all I can think off. Not too hard really. Get some of those quick cut cut wire stripping pliers and some Knipex professional crimping pliers, and a heat gun, should be done in no time.

most of the time you can just use heat shrink crimps and convert most of the plugs over. Microtech has a wiring diagram and installation guide on their website.

thanks for the input guys. and you forgot about the omp but i was going to delete that.

There really is no way to run the omp with the microtech I believe. You might be able to keep just the wiring to the omp and keep the stock ecu side by side, but then you will still need to share the TPS signal, bc you use the full range tps that the s5 omp normally uses.

Best way would be to use an s4 front cover, and mount the s4 omp on. Then you will still need an s4 turbo throttle body to butcher with an s5 turbo one so that you can connect the s4 omp linkage.

I got mine to work that way. (S5 TB with s4 OMP)
