Help with stock EFI

I forgot to add this, all of my wiring was done at the back side of the PDC. The engine side of the harness is 100% stock. I started with a PDC removed from a running truck and kept everything from the pdc to the engine as it was. The harness was cut on the vehicle side of the pdc if that makes sense.

That’s what I have. Everything from the pdc to the engine and computer is untouched. I cut the wires off that leave the pdc to the truck cab at the firewall and the took the obdII port out. I think I’ll mount ubd under the hood near the pdc. I’m not going to tear into the back of the pdc until I hear it run. Then I’ll start weeding out unused wires.
