Hi Can anyone help ? Got 1995 a4 1.8 and donor 1.8 turbo 1998. Want to put turbo engine in. Only problem not sure about is wiring. Would I have to swap the whole car wiring loom ? The instrument cluster wire up different. Was hoping to put ecu and cluster in from donor car. Can I connect ecu to main car wiring and do something with the immobliser in the cluster.
