the engine harness was pretty much the only thing that was swappedHow much of the wiring was swapped?

Cranks OK, but No Start Checklist for Fuel Injected 5.0 Mustangs model years 1986-1995 A word about this checklist before you start: it is arranged in a specific order to put the most likely failure items first.

When you're testing and you don't get the outcome that is predicted then you will need to repair and/or replace the wiring and sensors necessary to act right.
both red/green and red/blue wires are getting no power during run and starttfi isn't getting any power i found out, how would i go about fixing this?
you're absolutely right. the engine harness is obviously connected to the ecu, and connected all through the engine, it's then mostly connected through the starter solenoid. I'm only 18 and pretty inexperienced with this stuff so I'm learning as i go. is there something I'm missing?86 V8 engine harness and 92 body harnesses aren't really plug and play. There are differences in how certain circuits are wired. How exactly was the engine harness spliced in?
yes, i did install the wiring, and if I'm being honest i didn't know there was a computer harness i just connected it through what was left of the 92 wiring. i know the ignition switch has power in run, but when it's in start it seems to cut all power that it's sending out but it is still getting power from the big yellow wires.You have a 92 4cyl that you swapped a 86 V8 engine harness, does this include the computer harness?
I'm not sure about this, I guess I would start at the ignition switch looking for ignition power with the key on, you need a wiring diagram for both years to match up wiring.
Did you install the wiring?
it's okay, i got it running, it's hard to build a car with little money and a big dream, but i used what i had and i made it work. just takes time. problem was I didn't have power when cranking, i spliced wt/pnk with grn/red and it works nowYou need an ECU harness from a 92/93 car if you want to make things a lot simpler. Do a search as there are a lot of references on properly swapping these cars.
