Delphi MT88 PCM Bench Harness Info Etc

[xx_ED_xx]

I ended up with this pcm (see pics) running a fairly new big block. year model 2017.
The very limited info I could find about this pcm seems it was also used on some GM crate engines etc.
I am hoping to make an information thread. As well as a bench harness to read it "hopefully"
Feel free to add info if you know anything about these pcms.
Thanks

J2-13=switched 12v+
J2-28=switched 12v+
J2-73= gnd

These ECM's are not running any software like what GM Delphi ECM's have, many of them use some form of J1939 comms (like the MEFI ECM's did), sorry but EFILive probably will not even talk to this ECM even if you get the bench harness wired up correctly.

Thanks GMPX, I was thinking since it has similar plugs to a e67 either converting it or using a whatever pcm the gas 6.0's uses in the newer trucks. I was cross referencing wiring vs an L96 pcm pinout and so far a lot of things are similar.
