Need Wiring Diagram For PCM

Hey to all,

I have a 2005 F250 with a 5.4L 3V engine. I have been getting a CPS fault code. I have replaced both sensors and checked the alternator. I found a test procedure which had me disconnect the wires from the PCM and the sensors and check for voltage with the key on. It states that I should have less than 1volt on the + of the sensor harness at this point. I actually have almost 4 volts which indicates a short in the wiring harness. I need to trace the wiring through the harness and would like to know if any other devices share the suspect wire. I have been trying to find a copy of the wiring diagram but not having any luck. Would anyone happen to have a copy to share or know where I may find one?
