Im putting a complete engine and tranny from a 97 gtp into a 2000 gt. I wanted to know if i have to change anywireing harneses or if there the same. Is there a two peice to the harness. Ill be putting the gtp pcm in aswell. My only concern is the wireing harness and the two stage fuel pump . Do i need a gtp fuel pump or is the gt good enough for the supercharged engine. Let me know if theres anything else i need to change in order for everything to work well thanks
