I read on another forum if you switch it requires some repinning? Does anyone have a diagram for the repinning? I may end up buying the correct computer for my harness later but for the time being I'd like to repin it correctly.

Here's a thread with $61 1228746 wiring diagrams, you'd be better off keeping it as it's a more popular used ECM in F and B body cars.

The 12287747 is $4F and we don't have a thread for it, just looked in my computer and no wiring diagrams? Here's a link to most ECMs with info on each.
