I assume into an sn95? All the wiring and computer for coyote engine. Holley now makes the computer and harness for them, as well as modulars. Aftermarket K-member helps, not 100% sure if its needed. Special Coyote headers into an sn95 is needed..iirc $500. Electronic pedal.
This swap makes all the sence in the world cause of power output on 87octane. Absolutely phenomenal if you ask me!! Most swappers LKQ a truck coyote and order the brains/spinal cords new for a mustang. That Holley system out now is really advanced over the stock setup. Tuner friendly, but spend $2000+ for the setup(WELL WORTH IT for the track)
