swapping from 4age to 4agze or visa verca in a aw11 the only wiring that is changed is from the ecu to engine harness and it all plugs into the existing body harness.
i couldnt see any reason why you would need to swap out any of the body/dash wiring? the 4age engine harness should be rights plug straight into the existing body harness.
i'm sure anyone that's done it will chime in and correct me.
