Default ecm help needed again.

Ok I have a 03 6.0l/th400 in my 67 ChevyII. I got the motor from a salvage yard. I did not get the ecm that came with the truck. Nor did I get the vin#. I pulled the harness from a 2000 suburban. I removed all the unnecessary pins from the harness. I feel 90% confident its properly wired correct. Im using a 05 truck intake because of the larger injectors. Now im ready to fire it up. I have a ecm that I picked up serv# 09354896 hdw#16220610. This ecm is a non vats delete. Ive been told by a couple of people that I should be able to use any vats deleted ecm to start the car. Is this true? I have called several shops for help and I keep hearing Frankenstein setup? Is it possible this set up I have can be set up and run?

Can any one please help me out? Im losing faith real quick.
Thank you.

Your pcm is an older version of the "411" pcm. So provided you have it wired correctly and tuned, it should run.
