2002 mustang GT 2 valve swap to 1999 4 valve
Hey, been up to my eye balls in this swap. I have a completely hand built 4 valve motor that I just had dropped into my 2002 mustang GT. Though how do you wire this type of engine to the GT computer? I've heard that I can splice into my existing wiring harness, but I've also heard that I can re wire the whole car. Both seem like a chore, but which is the best route to go? I'm on the final steps of this project and really need help. Let me know what advice you have for me.
