I tried to search this using a lot of different terms, but I was surprised that I couldn't find the answer, because surely this has been discussed. I'm looking to swap an 04 crown vic police interceptor motor into a 97 thunderbird with the stock 2v. I assume it would be a straightforward swap, but I'm wondering if I can use my existing wiring harness and ecu from the 97? If I can, will I need a new tune? I'm really looking for the largest power increase available and still have a direct swap. maybe I'm barking up the wrong tree. if so, set me straight. Thanks guys.
