If you haven't destroyed them already, keep all of the wiring harness looms from the truck. ALL OF THEM, including the engine wiring harness and the one that runs back to the fuel tank. Also the one across the dash that hooks to the computer. This will give you all the wiring and connectors you need to hook to the various sensors and controls.
You will need to have an electric fuel pump capable of 9 to 13 lbs of pressure. You should run an O2 sensor, but isn't absolutely required. Computer will go into default mode without it and engine will just use more fuel.
