454 carbed motor to 454 mag EFI complete motor swap
I've swapped out my 454 carbureted engine with a complete 454mag EFI, I thought this was connect fuel line, plug in engine harness and it should run right! I have spark, fuel pressure, but no power to the ECM? I'm looking for a wiring diagram to find ECM power supply, and ideas?

Thanks, that will help a lot! I had looked at the fuse, and it looked ok, but I didn't put a volt meter on it!
