Anyone have the printout for both 4.7 and 5.7 PCM? Or know a source for such information?

I'm trying to replace the 5.7 PCM with a 4.7 PCM which has no "Fly by Wire" function. This could also be useful for those who thought of changing their PCM to a more friendly one.

Thanks,

Are you looking for a pinout of each connector at the pcm or a schematic for both hemi and 4.7 pcms? I can get both diagrams either way, just wasn't sure what you needed

I'm going to have to identify the pinouts for each PCM. I looked at the service manual and found the same pins on the C2 plug used for different functions so it looks like I'll have to go through all the pins to be sure.

Thanks,
