i am getting a turbo swap for my 88 non turbo car. what do i need to do for the wiring and ecu.can i use a non turbo wiring on a turbo engine. is there anyway to convert harness to turbo

 

first thing to do is dont ever be affraid to click on that button that says "search", it is surprisingly friendly and very easy to use. Just type in HAILERS S4 HARNESS and be prepared for a lot of reading

second thing (after reading tons of info) is that you will find it very easy to use the turbo ecu with your stock na wiring and new s4 turbo motor.

third thing: this thread will be closed in 14 seconds

The na harness will connect up to the turbo engine with just some common sense alterations. Like lengthening the BAC plugs two wires so it'll reach over to the right side of the engine.

The other thing that comes to mind is the twin scroll solenoid that controls the twin scroll. Remember that if you don't address this, the twin scroll will fail to the wide open position anyway and you'll have full boost anyway. But if you want the solenoid to work as designed you just move a couple of wires around.
