ok so i'm thinking about buying my old t2 back from a freind but i need a engine wireing harness. i've looked on ebay no luck, can i use a non turbo harness? or one from a s5?

 

If the car is an S4 and you are wiring in an S4 TII then it will work with a Little modification.the Wires for the injectors need to be lenghthened,and aalso you have to Wire in a Boost sensor.The S5 wiring Will do into the S4 but it is a Wiring job from hell,so be prepared to go Stand alone on this...Hit up the Search button for more info,and also Look Under the Quick reply Box..there are always more threads that are related,as anything asked on This forum,In one way or another,has been covered in so many ways..good luck..and welcome.
