First off I don't know much about the electronic end of my swap, but I put a vortec 350 in a 1992 camaro rs replacing the 3.1 v6 had my wiring merged with the trucks harness and had plans to use pcm 0411. I was given a pcm with the engine buy and my new harness connectors do plug into this pcm. If it plugs in no problem could there be a chance this is the correct pcm? Or did they make the casing and connectors the same for all cars and trucks around those years and by chance I could have one that's not 0411? Here's my thing I have the engine in car all connectors plug in where needed I have got the car to get power, not at the point of starting it tho trying to get fuel pump to prime and the ecm under hood blows when i hook the battery up. I know it's the orange wire that powers fuel relay and sends power to pcm I believe and oil pressure sensor. The pcm is the one blowing the fuse. Can anyone point me in a direction to figure out what the issue may be?

The Service Number (SERV. NO.) is what ID's the ECM/PCM. So no, not a 0411 PCM.

Okay thank you, I've been researching and came across the correct pcm part number I need ending in 0411 and will purchase one to see if that helps

okay so i got the correct pcm and it does not blow the ecm fuse underhood so thats great, i couldnt get fuel pump to prime tho, Does pcm tell fuel pump to prime?

yes
