I need to know if there is anything special. I am going to be putting an Na engine harness on my TII. Someone on here told me they did it and i only had to run a knock sensor. I want to know if this is true and if not, what should i do? Thanks

Are you running a TII motor or NA Motor?

 

I am using one... S5 T2 motor and S4 T2 ecu with a S4 NA harness.

I have only the basic sensors and no OMP so it works. I doubt it would work with every solenoid and sensor hooked up.

 

well, i have an S5 TII motor and i have 2 cut harnesses...i want to know what i should do, i've been trying to get any s5 harness, na or Turbo

 

Simple. Just download the pinouts for the non-turbo engine and the turbo engine. Put both sheets side by side. Go down the list for each pin of the ECU. There are not more than approx four pinout differences. Adjust the harnss that your to install to fit the engine you have in the car. Been there, done that on a series four non-turbo to a turbo. Piece of cake. You'd have to be a whack job to change harnesses over this.

 

HAILERS knows his stuff, he helped me with my conversion.

I didnt have to change any pins because im not using any sensors that changed pin numbers. Just running really barebones things. TPS, pressure sensor, afm, CAS. I think thats it. I have an N332 ECU, it runs fine with all this stuff disconnected.
