sorry it took me so long but, i used motor, trans, harness, and ecm all from a 2008 i pinned a couple wires from harness to add cooling fans and i just had it tuned
ive done it you need complete engine and trans with harness and ecm all from same vehicle the only difference i came up with was fan wires i had to add them to harness, buth other than that it all works, i just had to get a custom drive shaft
