Oh HAIL, Ers, what EXACTLY do i need to do to use s4 na harness on s4 t2?
I need to know exactly what to do on this.
I got the car running but it runs like **** and seemingly very rich. I went to change the temp sensor wire and it still shows hot, so it means I am cutting all the wrong wires to repin this ****.
I might as well swap to NA harness just want to know EXACTLY what needs changing.

Extend the BAC plugs wires so they will reach the BAC on the Turbo motor. The BAC on a turbo mtr is on the other side of the motor vs non turbo.
MIGHT have to extend the TPS wires so the will reach. This could be overcome by making an extension harness of four new wires with spades and females on the end of the extention harness. The spades and females would mate into the stk TPS pigtail connector and the non turbo EM harensss TPS connector. I probably should have done that instead of extending the TPS wires on the EM harness.
Totally ignore the knock sensor on the turbo mtr.
If the car has pwr steering.........extract pin 1R from the ECU. Not a big deal if no pwr steering exists.
I'd not extend the wires for the air bypass solenoid on the non turbo engine to reach to where that item exists on the turbo mtr. It only works for 17sec on cold starting and adds little value.
The secondary injector wires will now route on the inside of the intake manifold. No wire extenson needed there.
That's about all that needs to be done. It's been a while. The way I determined things, was to compare the ECU pinouts for non turbo vs Turbo ECU from the CONTROL UNIT pages in the FSM.
Totally forget and ignore anything that is related to the KNOCK CONTROL UNIT and it's inputs/outputs. Not required at all.
