Aftermarket ECU and Crank/Fuel Signals?

Going to be doing PRO EFI 128 soon, but keeping the 411 PCM hooked up with minimal pins for local emissions testing (codes only).

What if anything do I need to retain in the 411 to make the truck crank and or prime fuel? Trying to pare down the factory harness to the minimum items.

TIA :)
