2001 ZX3 wiring diagram

I was looking for the wiring diagram of a 2001 Ford Focus ZX3. I am having trouble diagnosing a problem with my vehicle and would like to find the wiring diagram for it.

Readiness codes reset every time the vehicle is turned off. I need to know what wire is giving power to the PCM memory while the vehicle is turned off. Since right now it is losing its memory when the key is off.

B+ that is NOT controlled by the ignition or relay is what I believe is the failure. I do not want to replace the PCM without confirming this wiring to be good. Any help with finding PCM wiring diagrams would be great!!! I have tried Alldata and other online resources, they are all weak and incomplete. I believe Ford's schematics is the only way.

Thanks!
