TBI Wiring Harness Adaptability

[taklbury]

Hello everybody. I'm new to this website. I'm a CJ guy looking to upgrade to EFI on my 4.2. I'm a sucker for punishment and have decided to go the DIY route. I've done a fair amount of research and am currently in the process of sourcing parts for the project. This website is a wealth of information. Thank you!
My plan is to use a prepped 747 ECM. My question concerns the adaptability of TBI wiring harnesses to ECMs. Specifically, how difficult would it be to take a wiring harness form a 93-95 setup (blue and red ECM connectors, 16197427 ECM??) and use it with the 747.
1. Will the connectors readily fit the 747?
2. Assuming pins will have to be relocated, does anyone have access to the 427 wiring diagram?
I live in Boston and junk yard parts are proving to be scarce at best . I'm looking to broaden my search a little.

I think you missed all the FAQ's on here and on the binderplanet.

1. no
2. yes see the faq's on the binderplanet injection forum. See my sig.

If you have a harness already set up for a 16197427 pcm, then just go ahead and run that. Dont spend time trying to swap back to the older 7747 if your harness is set up for the newer ones. They were used on the V6's too. If the reason you want to run the 7747 is because you have one, and not a 7427, then I can fix that problem. I have a couple extra 7427's and I also have a V6 memcal chip for it. I can sell it to you for a good price.
