Ford Repair: 1996 f150 302 to 5.0L HO swap, firing order, original computer

Question
Hey Steve i have herd alot of different stories about this type of swap and figured i would get your opinion.  I have a 1996 f150 4x4 302 fuel injected.  I just bought a juiced up 5.0L HO fuel injected motor to swap into the truck.  I have been told i can swap manifolds to allow for the intake to be pointing in the right direction, and use the f150 computer and harness to run the HO as long as i change the firing order on my truck distributor to the HO order.  I have also herd that i must change the computer to a mustang computer to run the HO.  As you see my problem...conflicting advice both from top grade mechanics.  This is my daily driver so i want to be ready for the changes before i start the rip and tear. Will a f150 harness even take a mustang computer or would i have to change it all...hopefully none but I'm having my doubts .  Any advice for the swap would be greatly appreciated thanks.

Ryan-

  It actually sounds like you're pretty much on track as far as what you'll need to do.  I'm not too sure about the computer or the wiring...the only real problem I can see using the truck's original computer would be the firing order.  The wiring harness is a mystery to me...I never learned much about electrical systems so I avoid them like the plague.  I would be surprised if you had to end up replacing the entire harness, but I'm hesitant to say much more than that because I'm just not sure.  Hope this helps.
