FiTech EFI system

This is a crate engine, it’s said that they had it running on a dyno.
Set it up for the fitech to controll the ignition, followed the instructions in the manual before start up. Just wont ignite.
So we decided to take a step back and install a mopar orange box and dist.
I can’t find any diagram that show how the orange box is supposed to be wired with a fitech efi. The blue wire in the fitech is wired to the coil when fuel only and I also have a wire from the orange box to the coil.
It’s a fitech 600hp system with the FCC.
But I can’t say for sure that they had it run on the dyno, since I wasn’t present
at the dyno test. Next step is to have it run with a carb just to make sure.
