IIRC the DPC-421 is the PCM hardware family, aka has all the proper pins and physical internals, while the DAC2 or whatever is the tune. As long as the family is correct the engine will run fine, especially with a ZF6. With 4R100 the tunes matter more since they might be for the MT or the AT.

Oooook dudes, here's your dipchit story of 2018 to share with all your friends. John still rules...I do not.... apparently.
Years of OBS ownership had me looking at the wrong #30....under the hood....not under the dash.
Beers on me everyone....and a free ride in my super awesome truck that is now operational once I get more fuses...yeah, I am out of those too.

I think when you plugged the fuel bowl heater back in, it was just a matter of time before the fuse blew. I wrapped my plug in red electrical tape to kinda create a moment of reflection as to why the tape. You can also rebuild the FBH but from what I’ve it’s not worth the money especially since you’re Western bound.

The next time I have Forscan going, I will see if I can identify the code. I will not be pulling the PCM just to get a picture of the code though, that is for sure. The part number for my PCM and the one Wesley posted are identical though, not sure if the part numbers for all PCM's are the same with different codes or not.
