PATS types here: https://www.motorcraftservice.com/pdf/pats_job_aid.pdf
Yes, Ford used Type A in Rangers 1999/2000, separate module, above glove box
Then used Type E 2001-2004, PATS in PCM
Then switched to Type C or G with PATS in instrument cluster
Type A module was connected to starter relay directly so could cause a No Starter motor activation
I don't see that on Type C or G, I don't see a wire from instrument cluster to starter motor relay as seen in Type A
Starter interrupt comes from pin 2 on PCM in 2007 starter wiring
I do know if you unplug the instrument cluster in 2004 and up Ranger engine will not start, first year of the HEC(hybrid electronic cluster)
I don't think this was PATS related, the HEC and PCM are "married" so one won't work without the other, this was Ford's answer to the problem of people swapping in low mile odometers in to high mile vehicles, HEC and PCM both have odometer miles stored in memory, these must match on start up or no start, and if there is no communications to compare then also a no start
The "marrying" means each unit shares an RSA encryption Key number so they can "talk", if you swap in a different HEC or PCM then no communications because they have different RSA Key numbers
