I've got a early 99 gt with a non pi 4.6 and a t45.
Also, I'm gutting a 01 gt with a pi 4.6 and a tr3650.

Question: is this a simple drop in and go? Plug and play situation? I'm taking the harness from the firewall and everything attached to the motor and tranny, is the 99 non pi computer going to work...what else am I going to run into?

Thanks in advance

The PI engine is basically improved upper intake and a little hotter cams. The computer should work with the new set-up

1999 Mustangs are all PI. That’s how they all came from day #1. Non-PI was 96-98.


Did your engine get swapped? Or you just assuming it’s non-pi
