Default 2003 expedition v10 gas 6.8L

I suspect a bad wire from #8 cop to pcm or bad pcm. How can I get a harness &/or pcm pin diagram so I can do an ohm check? This is my Daughter and Son-in laws truck and needs fixed asap and we don't have any cash to waste. Symptoms are "missing" at idle and driving mode. Auto zone obd check gives one code (p0358). Changed cop from #8 to #9 re-set drove back to auto zone checked again same code (p0358) and ofcourse still missing. BTW does the Haynes manual show the diagram for this vehicle, Chilton was useless. Thanks for any help you can share.
