GTP 3800 Motor swap into 2001 Grand Prix SE 3.1 body

[HomeBoyShopnClub]

just bought a 2001 Pontiac Grand Prix for 700 dollars
3.1 automatic.
car runs great,just has an electrical issue, the car will jerk and the speedometer will go nuts.

anyway how would i go about swapping in a gtp 3800 supercharged motor?

i found a supercharged motor out of the same year gtp model automatic. will the motor and transmission bolt right up in the engine bay?
i know ill need the gtp computer, what about the wire harness?

just need a list of all the things ill need
thank you
