Converting from Classic FAST to Stock ECM Wiring

I have a car that has a Classic FAST system installed and I would like to go back to using a factory ECM. Can anyone tell me what it would take to do the wiring harness change over?

Thanks in advance...
Nothing unplug it and disconnect the wire from the map sensor that runs back to the maf under the hood, and re-connect the pink wire with black strip at the injector harness, But depending how fast the car is I would not go back the stock ecm.
Thanks. I did the Pink/Black wire connection, but didn't know about a MAP to MAF connestion.
