Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.In order for this swap to even work you are going to need to change the complete engine and transmission harness as well as the computer that goes with the engine. If that has not been done its not going to work.
