PCM "Connector Views" missing from Service Manual - Upstream O2 pinouts please

I data logged my upstream O2 sensors today and the driver's side one is completely flatlined (Bank2 sensor1). It's a new sensor. I verified that the Violet-Grey wire is supplying power to the sensor connector when the ignition switch is on. I would now like to disconnect the appropriate PCM connector and verify continuity of the other 5 wires from the PCM to the O2 sensor connector. I found the wiring diagram so I know what colour the wires should be, but "Cell 150 Connector Views" is missing from the online manual here:

Does anyone have this diagram? Also, which of the three PCM connectors would the wires be on? I could probably un-wrap the harness a bit and look for those wires, but there will probably be wires for other things that are the same colour. Any help would be greatly appreciated.

Unfortunately, that wiring isn't common knowledge. That online shop manual for the 2005-14 Mustang is known to be incomplete. You're probably just going to have to pay for a PDF version but at least you'll have a complete manual to rely on then.

Ok thanks. Do you know of a place where I can buy a complete pdf?

This may be of some help. For 2011-2014 S197s. Ironically, I just shared this like 5 minutes ago on another thread. Total coincidence.

Look in Section 24, page 8 of 11. A little tricky to decipher, you are just the person to do it!!!!!!!!!

Thanks, ya that's the wiring diagram I'm using and I recently figured out that the numbers along the far left are the terminal PIN numbers on the PCM. Combined with these diagrams I could figure it out pretty good. I'd still like to have a complete pdf of the manuals.

That diagram is brilliant. Have not seen that before. Much appreciated.

I'm glad that you found a PCM pin diagram in that manual.
You can buy pdf copies of a Ford service manual or wiring diagrams for any car thru various sellers. Some manuals will come with wiring diagrams but most will not and are sold separately. Some will only grant you access while others are totally downloadable. Official Ford versions will be very pricey. They can also be had on cd/dvd or USB drive. There are sites that aggregate multiple sellers like these:
2011 Ford Mustang Service Repair Manuals & PDF Download (onlineautorepair.net)
2011 Ford Mustang Service Repair Manuals & PDF Download (motorera.com)
A sampling of specific manual links from those sites:
Ford Mustang 2010-2012 Workshop Service Repair Manual - Tradebit
Ford Mustang 2011-2012 Service & Repair Workshop Manual Download PDF - Tradebit
This one specifically says that it comes with wiring diagrams:
2011 Ford Mustang repair manual - OEM Factory Servis Manual (factory-manuals.com)
Paper copies also exist. Ebay is often a good source for them but these sites have them new or used:
