I switched one to a carb many years ago. What exactly are you trying to figure out?

I realize I can just pull the main wires and plug on the ECU. Thats easy. I'm not sure what else needs to be unplugged.. What the heck are these wire and can I ditch them. THey're right by the ECU.
I don't need the fuel pump. wiring (Sniper runs that independent ). Don't need an ignition source, I dropped an HEI in.
These are my stumbling

The fords are pretty standard across the board, Mustang, truck, T-Bird, CR, etc. In my experience:

The yellow is Battery + for the PCM
The red is Switched + for the PCM
If the other one is Tan?Green then it is the Fuel pump.

You can trace the yellow and red back to the relay behind the battery to verify.

Thanks for the tips. You were correct. I got it to turn over, but my battery was pretty dead. But, at least the wiring is figured out. Any luck I should be able to start it tomorrow . Need some gas and a hot battery...
