So i have an aluminum gen 4 5.3l that im trying to throw into an old dodge truck. I have a 2000 4l60e to go behind it. My question is, what kind of pcm and harness do i need for this? I dont really know much about the wiring part of this. I do have a 2001 silverado wiring harness and pcm that were left over from a previous build. could i use this stuff by chance? it was a 24x crank setup and i believe the new one is 58x.thanks guys!
