i have a 2001 F150 super cab 4x4 with a 5.4 v8. I blew the motor, so i bought a wrecked 2003 F150 harley davidson with a 5.4 (supercharged) The question is about the computer/ wiring harness. The motor is in the truck and i changed the engine management computer. Is that all i need to change? Thanks, Tom
