im doing an s5 turbo swap in to my s4 na and my front harness obviously is hooking up, how can i get an s5 harness or atleast the connector so i can rewire it?

im haveing the same problem

 

You are gonna have one HELL of a time doin it..it involves basically rewiring a Bunch of Stuff.Use SEARCH and type in S5 into S4..either that or you may try Using a Standalone system...it is NOT a Plug and Play Swap..I hate to tell you that,but them is the Brakes!..Good luck though,as I am going to be doing the same next year(so I am not gonna say anything Bad!..).

 

You do a Advanced SEARCH for the name LUCIU$ in the Second Generation and once you find his detailed thread.........you won't understand it unless you have read the series four and five wiring diagrams, and if you had done that you wouldn't be writing a thread asking, so...........forget it.

 

haltech time

 

sounds like its isnt as easy as just using the S5 engine harness and ECU... i glad i sold my FC earlier this year

 

well, i just ordered a haltech, but that hooks up to the harness that controls the gauge cluster and what not? the engine harness for the s5 tii is fine. its just the harness that runs the interior. like the radio and gauges.

 

Why don't you guys just use the stock series four EM harness and a series four turbo ECU? And either premix or change the front cover from series five to series four plus get a series four turboII throttle body (mech omp linkage attachment).

In other words use the wiring in your stock series four na plus swapping the front cover and throttle body of the series five to a series four turbo throttle body? Cheaper than a whatever tech.

And far be it for me to say for sure, but I think that haltech connects to the engine and the coils and the cas and the on and on.

Even better, dump the car and get a kite and go fly it. Jpg attached.
