Default 77-81 Trans Am engine harness interchange

I have an 81 TA which is apparently the first year for the emission control computer. The car had a 301 turbo in it originally and someone transplanted a 77 400 in there sometime in the 90's. The harness has the weathertite plugs from the turbo and emissions stuff on it. I unplugged the computer last night and the car did run and start, I looked at the wiring diagram and it looks like the only component needed that came out of the computer is neutral switch... the diagram didn't say neutral safety switch. I would like to put a 77 or 78 engine wire harness on it. Any takers on this one? You cant return a $200 harness..LOL.
