Hi again guys. We have a problem, well.. another one.
The customer sourced a harness and ECU. It was like christmas, ECU, sensors, injectors and harness all nicely packed in one box.
The problem arrived at the point when we realized that the body harness interface on the new N370 numbered ECU would not plug into the car's N333 ECU.
What is the N370 from? We assumed that this kid would have bought the same parts and we're trying to decide on either repairing the old harness or trying to continue with the new one, which seems unlikely since we have no flying lead connector from the new N370 ECU.
If anyone's interested in the above N370 package, as an aside, we paid $400.
Thanks,
Alex

wow what a mess, the n370 is the s5 ECU, you'd need the s5 harness to make it doable and then I don't know what issues you would run into with the motor, can't tell if it's s4 or s5 but from the omp setup maybe s5?
n333 is 88t2 and n332 is 87t2
89 to 91 n370

Ok you have an S4 car high impedance with a S5 motor!
If the emissions harness has 2 ECU plugs it is a S4 harness.
If the emissions harness had 1plug it is an S5 harness.
So you will need both FSM wire diagrams when you figure out what harnesses and ECU you are going to wire into this car.
I have already posted a pin out for you above. Here you can grab the FSM and compare wire colors. http://208.62.166.66:82/guest/shop_manuals/
Note the S5 motor uses a wide range TPS the S4 uses a narrow range TPS. The S5 uses an electric OMP controlled from ECU and the S4 uses a mechanical controlled from lever attached to TB.
The injector impedance is decided only by the resistor pack on the emissions harness pics are shown in my last post.
The S4 will also have a solenoid for the twin scroll just disregard it is bright green.

np, I figured I would take some guess work of it this for you and fill you in on the best rout.
Use a S5 emissions harness and ECU. Label each wire by its pin number; stick a needle in the back and depin it. Pull the tab back for repining, pin them all back into the S5 clips as labeled and per the diagram ^. Be sure to check each wire origin for comparison there is a couple differences.
I barely know anything about S5 so I won’t be much more help sorry.

Its got an s5 turbo manifold on it also, probably a complete s5 engine.
but I didnt see an airpump or belt for it and it didt have a double ribbed alty belt...

No FC had a double ribbed ALT. The belt for the air pump is the missing belt on the water pump pulley.
