This would require being able to get all the wiring harness and the computer. I'll have to check if he has all that. If not, could I just have my 99 tuned for the new engine/transmission?

Edit: Just checked and it is from a 2005. I thought it was from a 2004. Does this make a difference or still just swap engine/tranny/and engine computer?
