Been told a few things today about switching the ecu from from 2002 cougar to a 1999 svt contour. I am switching the engine over but retaining the cougar harness. I will use the cougar ecu to get the car running but was wondering if when I go to switch the pcm and injectors, can I just pop the new pcm into my car and tape the transponder to the dash? someone recomended this to me. I would just get a tune but cannot afford one right now.
