2015 ford transit no crank/no start UPDATE

One other symptom I had not thought about. when I turn the key on the radio comes on, I turn the radio off but the next time I turn the key on the radio comes on again
I believe that the ACM receives power, from Fuse 29, (which receives its power from Pin 37), when the key is turned to the "ON" position. The way Service Information labels Fuse 29 backs this theory up.

I am going out now to get the van in the air and check out the wire damage.
A point of interest- the injectors flash a noid light but the plug coil connectors do not

The pin with the White/Green wire (2) gets power from Pin 37 of the PCM when the key is in the ACC or RUN position.
The pin with the Yellow wire (1) gets a Ground from Pin 7 of the PCM when the key is in the START position.

Powertrain Control Module (PCM)
The PCM provides power and ground to the starter relay to initiate cranking of the engine.
Starting System
The starting system controls the cranking of the engine. Under normal operation, when the ignition is turned to START, the PCM receives the following inputs:
Request to crank engine message from the BCM
PATS enable message from the BCM
Correct transmission park or neutral input from the automatic transmission
When the PCM receives the correct inputs, voltage and ground is supplied to the starter relay coil. When the starter relay coil is energized, it provides voltage to the starter solenoid, allowing the starter motor to crank the engine.
The PCM disengages the starter once an engine Revolutions Per Minute (RPM) threshold is reached, a set crank time is exceeded or the ignition is turned OFF.
Passive Anti-theft System (PATS)
This vehicle may be equipped with PATS . PATS disables the engine from starting if an unprogrammed PATS key is used or an invalid PCM ID is received. The PATS is controlled by the BCM . If there is a PATS concern that disables the engine, the IPC displays a corresponding message in the message center.

By the way Chad, where do you get those nice wiring diagrams. I have taken the steering column apart and I do not have a PATS tranduce in the system.
