What PCM do I have?
Its a RED BLUE Warren PCM.
The service number is 09354896. This leads me to believe the PCM to be a 99-00. I know the engine is from an 02 burban.
The hardware number is what I cannot decypher. 09380120. This hasn't popped up on any ls derived charts I've found.
What PCM do I have?! Can I even use it?
However, I would swap to a 411 PCM.
According to this thead, a 896 can be upgraded to a 411:

Once you upgrade to the 3 BAR OS, they are identical.
What is going to be important is the Operating System currently loaded onto your 4896. Not all are upgradeable to 3 BAR. So you need to read it with HPT and see.
You might have to load an OS that is upgradeable.
