I havent read the manual [yet] but you would need
1-+12v and ground
2-starter +12v and solenoid wire to ign switch
3- +12v switched [ign switch]
4- +12v to fuel pump from ecm
everything else is wired to the ecm which is bolted to the intake manifold.
I guess a donor truck would be the way to go. Lots of engines[$1800 to $2500 ]in wreckers but no trucks I could afford. \:\)
