Ok I did the turbo swap (as most of you know) and I did a s4 n/a to s4 t2 swap

I am curious if I need to swap any wires or pins from the harness at the ecu

I do NOT have power steering
I am NOT using the twin scroll
I am NOT using the BAC valve, thermowax, dashpot
I do NOT have A/C

as of now I installed the ecu and just clipped my harness in.. I am guessing I wont have to change any wires but I just wanted to make sure...

thx in advance to those who can shed some light on this..


1 last thing... Last season I had my SAFC hooked up and wired into the harness for the n/a

do I have to move ANY of the wires for the SAFC to another wire on the harness.. Or do I have to add or remove any wires for the safc

 

I don't think you need to do anything given the list you made of things not used. SAFC connections are the same. I'm assuming you used the na harness on the engine. You MIGHT have to lengthen the TPS wires. Maybe, maybe not. Depends.

 

You are correct that is the one thing I did have to do was lenghten the tps wires... which is done... do I not have

So I take it the safc should be all set then and so should everythign else..

I appreciate the help Hailers

 

Plug and play buddy

 

I trust your using a Turbo ECU and Turbo boost sensor (one bar vs two bar sensors).

If you had used the twin scroll and also wanted the Air Bypass Solenoid to work then you'd have had to do some small wire movements.

If you wanted the Turbo knock sensor to work, you'd need to rearrange one or two wires and buy turbo knock sensor also and wire three wires to it. Not worth it imho. I've done it both ways and live without a knock sensor/box now.
