PCM memory issue

[Luke wills]

I noticed every time on turn off my truck my pcm resets so I have to redo all my drive cycles and everything? Whats causing this to happen? I went through all the grounds and cleaned them and checked the wires and nothing. Could it be a bad PCM?

Tried checking the positive side?

All grounds between chassis, engine and body need to be intact.

Crud in the main fuse box perhaps?

Main fuse box is clean and also the one in the cab. Im not 100% where the positives wires are.

Maybe the memory fuse is blown?

Believe it or not im having trouble finding it. I googled it and nothing . But the owner before me swapped out the 3.0 for the 4.0 and not sure if he switched the PCM ?
