Looking for others that have delve deep into the wiring schematics for the 100 series.

I have been running some diag on the ecm of a '99 and have been finding some discrepancies in what Toyota claims the voltages should be at certain pinouts.
I'll find in one section of a modules terminal layout a set voltage requirement and in another section of the manual it will have another voltage request. For example, one section will call for batt voltage (10-14v) and another will look for 3-5 volts.

I have been using the downloads made available on this site but I also have a shop account with Mitchell On-demand. The Mitchell doesn't have as much info regarding the terminal layouts and voltages so I have been relying on the free downloads. I'm assuming that these are copies of the factory manuals?

Thanks all
